uneedav8 Posted March 16, 2007 Posted March 16, 2007 On radiators, it seems most of the articles I have read say that its better to have fans pulling heat away from the radiator as opposed to pushing air through. What about having both?? Is it just adding more noise to have a push fan or do you guys think it will improve cooling? Share this post Link to post Share on other sites More sharing options...
Coors Posted March 16, 2007 Posted March 16, 2007 It could probably help a little but the only way to be sure is to just try it out and see if it lowers your temps. My guess is that it would add more air noise than it would be worth even if you got slighlty lower temps. OT: Who is that in your sig? He looks sorta like Mad Max.

ooeric Posted March 17, 2007 Posted March 17, 2007 pull. always pull with a spacer b/w fan. venturi effect. must seal the gap b/w rad and fan shut uses 100% rad surface area Share this post Link to post Share on other sites More sharing options...
radodrill Posted March 17, 2007 Posted March 17, 2007 Unless you're near the limiting heat transfer capabilities of the RAD; there won't be any major difference between push or pull. However, Pull definitely is more efficient than push. Share this post Link to post Share on other sites More sharing options...
ooeric Posted March 17, 2007 Posted March 17, 2007 with high pressure fans . there is a difference. maybe .5 degrees or so. there is a difference b/w high pressure fan and high cfm fan. Share this post Link to post Share on other sites More sharing options...
uneedav8 Posted March 20, 2007 Posted March 20, 2007 pull. always pull with a spacer b/w fan. venturi effect. must seal the gap b/w rad and fan shut uses 100% rad surface area Thanks for that idea. I have read about the venturi effect but never really tried it out. What I did was use an old 120mm fan and cut out the fan in the middle and use that as a spacer between the fan and the radiator. Right away....there was a noticable 2-3 degree difference and it is now quieter too Share this post Link to post Share on other sites More sharing options...
Guest thespin Posted March 20, 2007 Posted March 20, 2007 I am surprised by what I read here ... I read that having the fan blowing air thru the radiator is better. But if a shroud is used that doesn't leak I can't see much of a difference ... Share this post Link to post Share on other sites More sharing options...
MACarter02 Posted March 20, 2007 Posted March 20, 2007 I have both push and pull. Both are Yate Loon 120mm fans on a fan controller. Processor at 2850 MHz, 1.45 VCore Readings taken in Everest Ultimate Ver. 3.5 Here are my current temperatures: Idle Pull Fan only: Push fan: OFF Pull Fan: ~6V Ambient: 24.7C CPU Temp: 30C Push fan: OFF Pull Fan: ~12V Ambient: 24.7C CPU Temp: 29C Push Fan only: Push fan: ~6V Pull Fan: OFF Ambient: 24.8C CPU Temp: 32C Push fan: ~12V Pull Fan: OFF Ambient: 24.7C CPU Temp: 31C Both Fans: Push fan: ~6V Pull Fan: ~6V Ambient: 24.7C CPU Temp: 29C Push fan: ~12V Pull Fan: ~12V Ambient: 24.7C CPU Temp: 29C Temps fluctuated as you may expect, but I saw nearly constant 29C in jet engine mode, with both fans on full blast. For the Load testing, I used Orthos, small FFTs in an effort to leave my RAM out of the torture. Load Pull Fan Only: Push Fan: Off Pull Fan: ~6V Ambient: 24.7C CPU Temp: 41C Push Fan: Off Pull Fan: ~12V Ambient: 24.7C CPU Temp: 40C Push Fan Only: Push Fan: ~6V Pull Fan: Off Ambient: 24.7C CPU Temp: 42C Push Fan: ~12V Pull Fan: Off Ambient: 24.7C CPU Temp: 42C Both Fans: Push Fan: ~6V Pull Fan: ~6V Ambient: 24.7C CPU Temp: 41C Push Fan: ~12V Pull Fan: ~12V Ambient: 24.7C CPU Temp: 41C I actually hit 39C once or twice with the Pull fan only configuration at full blast. However, I did observe that with both fans on, my chipset temperature was lower. This is like because I have the HR-05 SLI mounted directly in the path of the airflow of these fans.

Coors Posted March 20, 2007 Posted March 20, 2007 Good post^^^. So a pull configuration will show a little bit better results. And even better results with both. I just got my new fans today but it is only possible to do a push configuration because of their design. But i'll be using a fan shroud so no worrys. Maybe i'll add three more fans to pull.
