Cooling PWM on Abit NF-M2 nView?

[DrMrLordX]

I'm messing with an Abit NF-M2 nView, and during testing, the PWM gets pretty hot when I start pouring heavier volts into the board. Right now I've gotten it as high as 54C.

I've done some reading, and it seems that temps of that level aren't a major threat to chip life or stability, but it's skirting the edge . . . can anyone tell me where the PWM is located on the board and what cooling solutions I should consider? Currently my test rig is in a Centurion 5 cooled by an 86.5 cfm exhaust fan and a Big Typhoon + Silverstone FM-121 (110 cfm) both running at full speed. I can't identify the PWM by feeling around for the hot heatsink on the board, because none of them really get very warm.

The PWM seems to heat up slowly and cool down slowly . . . makes me wonder what kind of airflow it's really getting.

54C is nothing for PWM & it's usually the hottest part of a mobo so don't worry.
fyi though it's under the big heatsink top l/h of the board that says silentOTES on it.

Oh okay, it's already getting cooled by both my HSF and exhaust fan. Thanks for the tip.

And yes, I have heard that PWMs are often rated for temps as high as 120-150C . .. I'm just trying to keep mine below 70C if possible. So far, it has not been a problem.
