CPU/Motherboard Backplate Fan Results - Page 2

post #11 of 17
This is a good study and is of interest to me. (+rep)

I did a similar study before and my findings were similar to yours.
I found that the CPU core temperature drops by only 1C. The Asus Stack Cool 2 plate (more or less represents the CPU socket temp) drops by 5C.

If you are interested, read for details here:-

Once again, I'm happy to see this.
I have the same case, and may replace the slim 120mm just to see what I can drop in socket temps.
I don't imagine it will be much, but it's fun to try.

Hey that link just links to this thread...


Well I could have scaled the pictures down but...I was in a hurry but more importantly it's the first real pictures I took with my new 14mp camera so there was no way I was going to do that unless I had to.

Funny thing about this is-you are not cooling the CPU backplate,you are cooling the backside of the VRM's.Don't believe me?Put your hand back there and feel where the heat is coming from.The VRM's will heat the back of the mobo way more than the CPU. It is beneficial however,other wise you might have fried your mobo already.

You are both right and wrong. You are right to say that the backside of the PWMs is being cooled by the fan but are wrong to say that the CPU socket backplate is not.

The fan underneath was blowing over the entire area. So, that portion of the motherboard under the PWMs was cooled (blue circled in pic 1). However, the backplate does not extend to that region. The backplate covers only the CPU socket area (yellow rectangle in pic 2). So, the backplate sinks the heat primarily from the CPU socket area. As the PWMs are further away, a little bit of heat might indirectly transferred via the motherboard PCB to the plate but the majority of their heat is carried away by the heatpipe heatsinks from above.

Those threads reminded me how much I wanted an IFX-10 heatsink......I need to find my ruler.......70mm above the motherboard....hmm.

(2 6/16) inches = 60.32500 millimeters

Hmm damn....that'd be really close.

70 millimeters = 2.75590551 in
