Q9450 Temps too high?

Did you get the backplate for the heatsink? You mightve incorrectly installed it or applied the thermal paste too thin or too thick. Wats the ambient temp in that room?

Heh, my q9450 idles around 49c at last check, but then again its been 90F lately and I have no AC. Even so, I had folding@home going 100% across all 4 cores + gpu folding for 5 days straight. No crashes or anything but the room was crazy hot, so no more of that in the summertime.

Guys,

When evaluating temperatures, since there are 101 variables involved, it's important to be sure that you're comparing Q9450 / Xigmatek apples to Q9450 / Xigmatek apples. Remember that when dicussing temperatures, there is a difference between CPU temperature (Tcase) and Core temperatures (Tjunction), so it's important to be specific as to which you are referring.

In a controlled testing environment, the ambient temperature is 22c, and when using a high-end air cooler, this should yield a calibrated CPU temperature of no less than 25c, and calibrated Core temperatures which average about 28c at Idle, (if the Digital Thermal Sensors - DTS - are working properly), with Speedstep enabled (Auto Vcore and 6x multiplier), and case covers removed with all fans at 100% RPM.

Most 45 nanometer DTS sensors begin to respond properly above 50c, so use Prime95 Small FFT's to evaluate Load temperatures. Again it's important to compare apples to apples, so be sure that ambient, Vcore, frequency, multiplier and cooling parameters remain constant. If you're comparing your Load temperatures when using overclocked settings such as manual Vcore and frequency, then be specific as to what your settings are.
