I noticed this morning, after running Memtest86+ 4.0 overnight for 7-8 hours, that my CPU temp was at 63 C in the bios and my stock CPU fan was running at around 2400 RPM. My fan was recently cleaned with a can of compressed air too about 2 hours before I started running Memtest86+.

I have 5 case fans, 6 if you count the huge one on the PSU.

Does it matter if the side panel of my case was off all night? Maybe this was preventing sufficient "air flow"?

This isn't normal is it?????

Ambient Temp: Around 22 C
CPU: Core 2 Duo E6400 2.13 GHZ
Mobo: Asus P5B Deluxe
Memory: 4x1gb Crucial Ballistix DDR2 PC6400

Normal CPU cooler is just the regular approved-by-Intel cooler. It's just a basic heatsink + cooler vertical that I paid around $10 for back in the day.

I will recheck with the case panel on later tonight.

jowww87,

Memtest is inappropriate for processor thermal testing. Prime95 Small FFT's is the Standard for thermal testing. Since saturation is typically reached within 7 to 8 minutes, a 10 minute test is adequate.

Also, there's a 5c difference between CPU temperature and Core temperature. Never assume that uncalibrated temperatures are accurate. Hardware Monitor will display both sets of processor temperatures, however, it can't be calibrated. SpeedFan will display and allow calibrations for both sets of temperatures. Real Temp will display and allow calibrations for Core temperatures only.

From the Core i7 and Core 2 Temperature Guide - http://www.tomshardware.com/forum/221745-29-sticky-core-core-temperature-guide

-Tcase/Tjunction-
--60--/--65--65-- Hot
--55--/--60--60-- Warm
--50--/--55--55--Safe <--
--25--/--30--30-- Cool

Tcase = CPU temperature
Tjunction = Core temperature
