klokan Posted November 25, 2011 Posted November 25, 2011 Hi. I need help about fan direction. It is about corsair 650D case + corsair h100 water cooling push/pull on top. a) push/pull suck hot case air but have slow 120mm noiseblocker 700rpm cool air help. Down right is 200mm slow fan pushing cool air on hdd, psu and graphic card (msi gtx560 ti hawk) b) push/pull push cool air into cooler, and worm into case. faster 120mm push worm air out. Down right is 200mm slow fan pushing cool air on hdd, psu and graphic card (msi gtx560 ti hawk) Which is better for less noise comp, not very high clock level? What fans do you reccomend, II was thinking about noiseblocker. Tnx p.s. i borrow pic from google, this is my new build in progress: ASUS P8Z68-V PRO Intel Corei7-2600K SSD Disk OCZ Solid 3 SATA III 2.5" 120Gb DDR3 Ram 4x 4GB Kingston HyperX MSI N560GTX-Ti Twin Frozr III HAWK Finished setup will be posted Share this post Link to post Share on other sites More sharing options...
paulktreg Posted November 25, 2011 Posted November 25, 2011 There's only one way to find out and that's try it both ways and monitor your temps! Share this post Link to post Share on other sites More sharing options...
cery25 Posted November 25, 2011 Posted November 25, 2011 (edited) Option B Edited November 25, 2011 by cery25 Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted November 25, 2011 Posted November 25, 2011 Option A You want the majority of heat outside your case, not in and back out. Share this post Link to post Share on other sites More sharing options...
Locutus Posted November 25, 2011 Posted November 25, 2011 Option A You want the majority of heat outside your case, not in and back out. Option A, but the exhaust fan at the back of the case pointing outwards. You want the air in your case to flow, not to go everywhere.

XD It would be true if he had air cooling. He has watercooling with the heat emanating from the radiators. I don't care if you have the best airflow in the world in a case, you don't bring heat inside your case so your airflow can take it back out. Keep the heat out, and you don't need to worry about great airflow. Share this post Link to post Share on other sites More sharing options...
klokan Posted November 25, 2011 Posted November 25, 2011 (edited) i have some electronic experience. I belive that option a) is the better option. the heat rises natural up, so it will be harder to cool with worm air..

Boinker Posted November 25, 2011 Posted November 25, 2011 Option a. Where you have the radiator heat will rise to it regardless until the heat overcomes the airflow. Best to have it in option a as the heat inside the case will stay down overall. I believe with it at option b you will run into a lack of exhaust and overheat everything else rather then help just the processor.

Waco Posted November 25, 2011 Posted November 25, 2011 I saw much lower CPU temps when I ran my radiator blowing into my case. It kept dust down too because of the positive pressure inside the case. So I'd go option B. Share this post Link to post Share on other sites More sharing options...

Rubeer is fine against noise, but not for air. Some sponge is good against noise but dust collector Share this post Link to post Share on other sites More sharing options...
VaporX Posted November 26, 2011 Posted November 26, 2011 You need to set the rear fan and top fans to exhasut. While the intake at the top might help the CPU temp, it is introducing the heat pulled from the CPU back into the system. By exhausting you might get a small increase in CPU temp but the heat is all pulled out of the case. Additionally by exhausting from the top you actually make the heatsink more effecient because you get a boost from the natural rise of the heat. One of the benefits of the liquid cooler over the traditional air cooler is the fact it dumps the heat out of the case, by pulling the air in you are negating one of the designs advantages.

klokan Posted November 26, 2011 Posted November 26, 2011 I think i will give up push/pull because of my mbo miss 5mm. Just read about it. (Unless i found quality and quiet 20mm fans.) If so, I think the best setup will be upper push intake with dust filters outside with rear fan on exhaust. Share this post Link to post Share on other sites More sharing options...
