Billy Cow. Hi, not sure what is best, decided on getting the Corsair 600C … TDuiker. The front mount lies in the middle in terms of cooling for the radiator. Wiki Points. NashaK. As suggested above, I would certainly set the H115i fans to exhaust heat out the top. Otherwise it can put undue stress on the fans and the bearings shortening its life span. I'm new to water cooling and just bought a corsair aio. The dust thing can't be overstated. Warm air pushed inside towards VRM and RAM (remedied by having rear exhaust). Top mount radiators - Intake or Exhaust fan setup? Who knows about the VRM/Mosfet though. Heat from the VRM and GPU make their way to the radiator. I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. Forum Regular reference: whrl.pl/RbyBDd. last updated – posted 2017-May-10, 10:52 am AEST posted 2017-May-10, 10:52 am AEST User #552599 36 posts. Im fitting a 3 fan radiator to my Cosmos S case at the top.. Whirlpool Enthusiast reference: whrl.pl/Re87Nq. Under low CPU load, the radiator acts as an airflow straightener without warming up the air, so the fan can blow cool air more effectively inside the case. either way, doesnt really matter too much. This topic is locked from further discussion. Considering the NZXT H440 has 3 front intake, you better off with two fans on the H105 exhausting out of the top of the case. last updated – posted 2008-Jun-26, 4:46 pm AEST posted 2008-Jun-26, 4:46 pm AEST User #183846 445 posts. This should provide more consistent results than using BOINC's Rosetta@Home. But all in all the difference arent that big as i would have thought. Planning on building a computer but need some advice? Followers. Discussion in 'Overclocking & Cooling' started by Jonnybmac, 11 Aug 2019. Exhaust fans at the rear can also cause airflow conflicts and do the most damage to radiator temperatures. With a lower overclock, I can finally test with AIDA64 using the FPU. Is that optimal for temps? I was thinking about trying something similar with the h220x I pre ordered... New comments cannot be posted and votes cannot be cast. For now I use 2 intake bottom, and 2 exhaust back and side. At 100% CPU load with my current overclock (4.6 GHz), my GPU seems to be running at least 3-5C hotter with the radiator mounted at the front. So i have these 2 options ( blue rectangles are intake fans, red are exhaust ) : However, you may need to invest in some air filters for the rear fan. Press question mark to learn the rest of the keyboard shortcuts. We’ll recap some of the most critical aspects here: Thermal tests were conducted using an Intel Core i7-6700K Skylake CPU and Z170 mITX platform, parts listed below. Worst performing of all setups. The manufacturer recommendation of having the radiator intake from the top is a good recommendation. NZXT Grid w/ Fractal Design 3-speed fan controller, Gigabyte EasyTune, Unigine Valley 1.0, Extreme HD preset, Windowed 1920 x 1080, 8xMSAA. März 2020; G. GushO Cadet 2nd Year. The temps will be affected significantly after a while for the top intake without any filtering in a dusty house. Under high CPU load, radiator blows warm/hot air inside the case, warming up GPU, VRM and other components. One was a gaming test, which consisted of me running 7 Days to Die standing in my base looking at my two forges until the temperatures leveled out (for some reason this taxes the system a lot). :] level 1. Loudest of all orientations. would it work better if the top radiator was intake and I made my front panel exhaust? was the head gasket blown or just the intake? However I'll be honest I haven't tested this inverted setup, which is why I said theoretically. Very muted fan noise, very faint pump noise. In fact, the Glacer/H220 is designed with this in mind with a reservoir and fill port that helps bleed the system of air when the screw faces up. Hot air rises, as well as the CPU in in that area of the case in a most common ATX set up. I'm new to water cooling and just bought a corsair aio. The AIO will either use the hot air from the gpu as cooling or expell hot air into the case and make the gpu run hotter. It doesn’t matter. A lot of builds do and there’s no issues, More posts from the watercooling community, Press J to jump to the feed. posted 2008-Jun-9, 4:09 pm AEST O.P. I ran two lots of tests. Usually it's recommended to have your aio mounted in the front in this situation as it significantly improves cpu temps while only worsening gpu temps a bit. I was in the same location for both tests. 6 years ago. Using radiator as intake on the other hand hardly effects GPU temps in game. This would be the same situation just inverted. Nice info. It does the best for noise too. I just can't decide if I want to set the H100i up as an intake with the fans below the radiator pulling down into the case, or if I want it set up as an exhaust with the fans above the radiator pulling up out of the case (I'm only suggesting pull configs because of easier dust cleaning). I have a Corsair H110 with stock fans and I run push intake with the radiator on top, exhaust out the rear 2 fans intake from the front. I would be mounting the radiator in the top of the case and would look like this setup. Joined: 17 Dec 2009 Posts: 1,881. The air coming out of the intake radiator is about the ambient temp + 60-70% of the water delta. In the midst of my aircooler and watercooling testing, I wanted to see how much of an effect radiator position had with airflow and temperature. posted 2017-May-9, 3:42 am AEST O.P. more intake than exhaust increases pressure in the case which forces air out the case faster as air always flows from regions of high pressure to regions of low pressure. The Glacer 240L is essentially a Swiftech H220 with Cooler Master Blade Master 2300 RPM fans, a faster pump, and no PWM splitter. Sorry if this sub is just meant for custom liquid cooling, this is the best place I thought I could ask. I will use the Noiseblocker Eloop B12-3 fans, as I found them to perform much like the other fans but with less noise. Top fan spaces are free to close off or add even more fans. Corsair recommends that you use it as an intake but then I'll have 3 120mm front intakes, 2 120mm top intakes and only one 140mm back exhaust. The 240mm radiator, however, is thicker and has tighter packed fins. The radiator gets the coolest airflow with the least airflow conflict. To conclude, it's all about finding which configuration works for you. Radiator intake or exhaust? On the intake side, I purchased a Minnam intake, for my OBS, used that cost me $20.00. Hallo, ich werde am Wochenende in das Lian Li PC-O11 Air 3x 30mm 360 Radiatoren einbauen. posted 2018-May-5, 5:51 pm AEST ref: whrl.pl/Re87Nq. Participant reference: whrl.pl/ReTrLh. (intake) or b) exhausting air from "inside" the case through the radiator and out the top of my case (exhaust) https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc Very nice, good read. Keep up the good work. does intake or exhaust matter for a radiator matter. I went with dual intakes and did some testing in my Define R6. So, if you want optimal overall temps, you should give your radiator fresh air. Radiators are kind of dust traps as it is, which is amplified when using as an intake and even further when it's the top, where dust naturally settles. Close. Should I be: a) pulling "fresh" air in from the top of my case through the radiator. I'm assuming we're not talking about blower cards despite it looking like there is one in your image. Anyone is welcome to seek the input of our helpful community as they piece together their desktop. 3 3. You'd think with "a couple degrees" difference between rad intake and exhaust, it wouldn't much matter having a radiator placed coincident with exhaust. I have a Caselabs S8 case with plenty of ventilation to pull cool air in. However, depending on the CPU load, the rest of the case may get warm air, which can hurt GPU and VRM temperatures. CPU block pump becomes the highest point in the watercooling loop and can trap air bubbles. Someone who overclocks very high, needs the coolest CPU temperatures, and doesn't mind the noise too much will benefit from having the radiator intake from the top. Silence freaks may mount the radiator to the front of a silence case, while someone who isn't too worried about maximum CPU overclocking but wants the GPU to run a bit cooler can do a radiator top exhaust. does intake or exhaust matter for a radiator matter. The other custom XT6 exhaust was around $500 including the header and a cat converter I supplied. Press J to jump to the feed. Top mounted radiator, intake or exhaust ? gm is supposed to have a better intake gasket set but last ones i bought a couple of months ago looked the same as i put in in 2005,plastic and some kind of rubber. Edit: this statement is actually correct. posted 2017-May-9, 3:42 am AEST ref: whrl.pl/ReTrLh. Cases with front doors benefit from sound damping. I had the fans in push (exhaust) under the radiator, but it got to be a pain removing the fans to clean cat hair buildup. This allows the radiator to get the coolest intake air from outside the system. Basically one of those things where it's just personal preference. posted 2008-Jun-9, 4:09 pm AEST ref: whrl.pl/RbyBDd. Archive View Return to standard view. This means you will have 3-4 intake and 3 exhaust giving you relatively balanced airflow and overall the best thermals you can realistically get. So pushing that hot air through a second rad is a waste of radiator space. Forum Posts. Rear exhaust fan steals air from radiator. Show only OP | 11 Aug 2019 at 21:47 #1. Intake v exhaust AIO radiator top mounted. But intake would be more ideal. Both components will be cooled the same. Filtered, fresh air from the front (though slightly restricted). OR having a few more intake than exhaust fans can be helpful. Wise Guy. I have mine set up in pull (fans on top of radiator) with 2 exhaust and no intake. Desweiteren sollen drei zusätzliche 120mm-Lüfter als Intake, zwei 80mm-Lüfter als Exhaust dienen. Hose and fan cables may not be long enough. All-in-One CPU-WaKü Radiator als intake oder exhaust. Theoretically yes. Results. I use the AIO Cooler Master ML120R, and the radiator is mounted on the back, fan exhaust from the inside of the case to the outside on the radiator. But .. and it's a big 'BUT' .. the exhaust side of a fan has impellers 4-5mm farther away from fan mounting surface (fan housing) then on intake side. I always thought the lack of proper airflow would tax the GPU temperatures way more. Note: I did some informal testing with pull setups. I would be mounting the radiator in the top of the case and would look like this setup. The commonly done configuration of having the radiator exhaust from the top doesn't bode too well for radiator cooling (but certainly helps GPU cooling a bit). Keep in mind the liquid temperature must be kept below about 45C or the lifespan would be greatly reduced. Jonnybmac. if the head gasket is blown also it will run hot quick. Intakes fresh air from the top, runs coolest. It's a trade-off between CPU and GPU temps. 0. Press question mark to learn the rest of the keyboard shortcuts, Fractal Design Define R4 (without window), Cooler Master Glacer 240L w/ 2 x Noiseblocker Eloop B12-3, Sapphire HD 7970 Dual-X @ 950 Mhz / 1500 Mhz. The GPU (GTX 980 Ti) was using an NVIDIA reference design cooler (blower fan), which will yield … I see every kind of setup on Reddit, but nothing seems to confirm that one is better than another. It's really just a disclaimer for the single radiator crowd who are likely to put the cooler in the rear exhaust, where it will also be affected by GPU waste heat. Ersteller des Themas GushO; Erstellungsdatum 5. 5. With the radiator at the front, the pump becomes the highest point in the loop and can trap air bubbles, making the pump noisier. Archive View Return to standard view. As the water temperature inside the loop moves fast enough, the the water temperature will be the same throughout the loop and there therefore no trade of. Doing God's work, /u/Pianowned. The radiator … The Revision 2 model I have has removable power cables, which addresses the problem the H220/Glacer had with fraying or damaged power cables that rendered the pump useless. will this make the cpu hot if hot gpu air is in the radiator? And I LOST hp and torque (around 10hp/10lb-ft, 2.5") with that setup because the diameter was too wide (It was my choosing). Question. The temp difference will be a few degrees at best realistically it will make zero difference in how your system runs. Posted by 5 days ago. If the radiator fans are exhausting, they would be pulling hot air from the gpu through the radiator. Im also using an aio as the example as if you've only got one radiator it is extremely comparable. So here goes! Radiator uses warm air. However at 4.6Ghz, the radiator and the air coming out of it is very warm and can heavily affect internal case temperatures. :]. The radiator core is offset so that the side with the fans allows fan screws to clear, while the opposite side has less clearance to allow larger fins for better heat dissipation. Reviews: 0. I think it's worth it for the sake of 2 degrees C and a load of convenience to go front intake or, for minimal effort, top exhaust. No airflow conflict with rear exhaust fan. A 120mm liquid cooler was used for the CPU. EXTREME Overclocking Forums > General CPU Cooling > Water Cooling - (Plain & Chilled): Radiator on intake vs exhaust side 2 x Fractal Design Silent R2 (front), Cougar Vortex HDB 140 (rear). Certain fans are noisy intaking through top venting. Lowest noise for those cases. posted 2018-May-5, 5:51 pm AEST O.P. If it's possible you could just put the radiator in the front and solve the problem the "normal" way. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. However, depending on the fan you use, you may incur a heavy noise penalty (the Noiseblocker Eloop is a great example of this). Top radiator is 360mm long. When people build custom loops, the pump is usually at a lower point and is constantly fed water by something like a reservoir to ensure quiet and reliable operation. Follow 11689. A really interessting test considering that top intake is the best cooling option in this case. 0. This is the place to ask! Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. H220/Glacer 240 specific: Fill port faces up, allowing air to bleed out slowly. Dabei seit Nov. 2019 Beiträge 18. Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. Many manufacturers recommend that the radiator be installed in a way that it can intake air from outside the case with the fans pushing air into it. Keep up the good work. Zarter. The water delta was 4.7C with the fans at 1650rpm and the case + front door open. i prefer more intake than exhaust, but thats because my silverstone raven 2 works better that way. the reason i ask is an intake will put exhaust in the radiator and make it use little water. Note 2: At 4.2Ghz, the processor does not warm the radiator enough to heavily affect GPU temperatures when the radiator is mounted at the front. You’d be fine placing your rad on top. Bottom radiator, intake or exhaust. While what MNMadman said might be true in rare cases, fan airflow is basically the result of the pressure differential between intake and exhaust sides of impeller, .. and as such impeller has no idea if radiator is in front or behind it. If you have filtered intakes elsewhere, though, would be fun to try it. If you have both exhaust and intake fans, you should ideally balance the volume of air moved. for a cm haf x, more more intake is better. So far, the only ready-to-run open loop cooler that tackles this issue is the Swiftech H220-X where the pump and reservoir are one and the same, mounted to the radiator. A bottom intake fan is recommended. Also, I have switched out the Noiseblockers in favor of the Noctua IndustrialPPC NF-F12 since the Noiseblockers exhibited very loud buzzing because of the fan grilles and filters at the front of the case. Glad to see my setup is optimal for my needs (and seeing as my hearing sucks noise isnt much of an issue for me), Doing God's work, /u/Pianowned. The result was slightly more fan noise and 1-2C higher temperatures. Question. last updated – posted 2018-May-6, 3:58 pm AEST posted 2018-May-6, 3:58 pm AEST User #207427 1705 posts. Take it on a case by case basis. Air stays trapped in the radiator and not at the pump. I'm getting a NZXT H440 and I was going to put the H105 in it but I can't figure out wether to use it as an exhaust or as an intake. /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. It's recommended that you remove or reverse the rear exhaust fan to provide fresh cooling to the radiator. Another benefit is that the radiator straightens airflow and increases airflow from the front fans. The full test methodology is available in the GamersNexus reviewand was used throughout this cooling optimization test. People will bring up the fact that hot air rises, but that is negated by forced airflow. Difficult install. Advanced Search; Forum; Cooling; Liquid Cooling; Top Radiator .. Intake or Exhaust? Air stays trapped at the radiator, not the pump. Hi all, I've been bouncing the pro's and con's of … Archive View Return to standard view. My current setup has a front mounted radiator as an exhaust and one 120mm fan in the back as intake and two 120mm fans on top as intake. Finally, many CLCs and ready-to-run open loop coolers (H220/Glacer 240L) have a pump/block combo which means the pump sits at a high point. Also, as per everyone else's recommendation, it is best to have exhaust fans on top or upper rear of the case. Hardly effects GPU temps in game airflow from the top is a subreddit...
