Are those the M1 and H1 fans respectively?? I have the H1 on my SLK-948U cooler (92mm fan) and from what people are telling me, it's giving me good temps... Of course, I want lower, but that might not be possible...
I've been running a Prime95 torture test for the past half hour and the max it's hit is 46C. It's ranging from 44-46C on the processor, and has been for a while... My idle temps range from about 30-34C depending on what else I have running... With some apps running, it's 33C, with different ones it's 34C...
Take that as you like... BUT, with the XP-90, you could see even better temps. Depending on what you do to your processor and which one it is.
