As the previous poster has said, if you want to use only one fan to cool everything, it shouldn't be the PSU's one. There are two main reasons, I think:
- The PSU fan normally is regulated depending on the PSU temp, so under low power loads it's gonna be probably too slow to handle the heat load of two CPUs, HDs and the PSU itself.
- The other way around, if such a heat load makes the fan spin faster, it could be actually worse, because the PSU fans at fast speeds are not exactly quiet or silent.
I'd say your best bet would be a similar design but using a quiet 12cm fan as a Nexus or SlipStream (was that the name to the low pressure Scythes?) instead the PSU, and place the PSU in the floor of the case drawing air from the bottom and exhausting to the back ala CM Cosmos, if you can rise the case a little from the floor. Then, the idea of placing the HDs after
the CPUs in the airflow path is really good, as they don't have the same cooling needs as CPUs that are critical, so its probably the best idea if you want to use only one fan.
I think that the PSU should be avoided as a case fan in any silent/quiet pc.
, I don't know what to say, but I am really interested because I'm just about to start building my own MDF/melamine (not yet decided) case, and I was thinking in 10mm board because of the final size. But now tehcrazybob
makes me hesitate... 1/2" are 12,5mm, and I can't get this... I think what I can buy is 10mm, next 16mm. 16mm means 1,2cm height more than 10mm, wooops... it's gonna be really a lot of difference? Will 10mm board do poorly?
(I'm gonna use 20mm Copopren - a noise isolating open cell synthetic agglomerated - in side panels and front panel and door, as depth and width are not a problem, only height)
Sorry if I've some little language mistakes, I do my best with english. And lots of luck with your project
Please, do not answer my question here except if you think is going to help the OP too. I don't want to hijack this thread with my own project so I will start my own, I have some other related questions too
