Is anyone using rear intake fan in your case?

[dodo]

In general we use one or two intake fan at front and one or two exhaust fan at rear. Can we opposite it say two intake fan at rear and two exhaust fan at front? I ask it because CPU is near the rear fan. If there is a fan directly blow the cool air to it we should get a lower CPU temperature. Am I right here?

Also is there any other combination here. I think hard drive also need a intake fan to blow the heat from it but it locats at front.

Any comments or experience?

Well, the default layout is as such becauyse it is the optimal case, usually. Fong Kai ships their FK-320 case with a 92mm fan as an intake, right above the CPU, with a shroud over the CPU. I've tested this case many ways, and with a "normal" heatsink, where it is blowing air into the pins/fins, having the 92mm fan set as an intake helps.

I really dont think having the front fans set as exhaust and the rear fans set to intake would help, however, because the front fans would be exhausting nothing, since warm air rises. However, if you were to have both front and rear fans set as intake, and have a side blowhole and a top blowhole both set as exhausts, that would probably be a good system.

Heh, My rear fan is an intake in my case, ................. just because its the only case fan i have besides the cpu fan of coarse, heh
Im not gonna bother doing any more cooling, im just gonna build a new system pretty soon

I have an SX830 (antec) with an intake in the front and the lower one in the rear. The top is an exhause and then I have the dual fan enermax powersupply. It is a couple degrees cooler on the cpu with the intake fan blowing on the heatsink. Try it you never know. Each setup is different

you want to have airflow moving from one side of the case to another so that all of the air gets circulated. if you put an intake in the back and have a psu that sucks air from the cpu area, then the nice cool air just gets pulled into the psu and spit back outside. if you really want to have intake in the back and you have a psu like this, you can always reverse the fans so that the psu is an intake (may be a bad idea, depending on how much heat your psu produces)

Thanks a lot for the infor. I will not use PSU fan as intake. That is the only fan I can feel blow out the heat air from the case, actually from psu itself. I will try reverse the lower back one to see what is the result. But theroically I am not sure whether that is good or not.
