fan behind CPU-backplate - Page 3

post #21 of 100
...I mounted a 100mm Scythe Kaze Jyu slim fan behind my motherboard tray / cpu socket in my old 800D build. I did not mod any ventilation in to the back of the case, and had it blowing air down on to the socket. The effect was negligible, however positive and would result in max 1 centigrade cooler with fan on at max rpm over temps without!

...in summary, it may reduce temperatures a little, but nothing really worth worrying about unless you have a case with a grill there already!

The Antec Three Hundred Two is an example of a case that has a fan blowing on the back of the CPU socket.

The panels were on hinges and were fined for additional surface area, and had heatpipes that extended off of them to land square on the cpu when shut. it only fit motherboards with standard cpu socket locations of course. Results were pretty terrible and costs were huge. It also weighed a ton.

I am not sure, but I think the fan needs to be pwm compatible, there are only 2 wires to that positive and negative so it's likely going to be full speed ahead.

ok i tried mine last night and it didnt make no difference frown.gif what i twant to point out though is that i have antec nine hundred (bought in 2009 so old version) case which has no hole that would make my backplate visible. the other thing is the metal is very thick (or feels like it is) and it doesnt even get that hot so there is no heat to be taken away really... i wish somebody with a case with the backplate hole tried it...

I think the thing is , at least you tried.
whatever method, the more heat you can draw away from the CPU the better it is.
