Wrong temp reading from Celeron 430? (Conroe-L)

Post by sircanegiem » Fri Oct 16, 2009 9:10 pm

I just put together a low-power PC for my sister and her husband using the Celeron 430 OC'd to 2.8GHz with the stock cooler and stock voltage. I installed it in a Gigabyte GA-EP43-UD3L motherboard. The case has two fans blowing air over the CPU.

The strange thing is that Speedfan and HWMonitor report the CPU's idle temp as 40ºC and full load at 63ºC. This CPU only has a TDP of 35w so it should only be half that! Intel lists the themal spec (the temp it should not exceed) of the CPU as only 60ºC, which makes me a little concerned. AND when I touch the heatsink, it barely feels warm, and after re-seating the heatsink twice with AS5 I know it's making proper contact.

Anyone heard of this? Strange imo, esp. with people posting videos on youtube showing their celeron 430 running without a heatsink. #-o

Well, the stock cooler is pretty pathetic. Have you tried dialling down your overclock?

Also, CPU temperatures are dependent on ambient and case temps. Inside a slim micro-ATX case, my Celeron 430 (running stock speed with stock cooler) was idling at 45C and load at 55C. Ambient temp was around 27C.

By the way, I've noticed the Pentium E5200 runs a wee bit cooler than the Celeron 430.
