Intel E8600 overheating 50C (Speedfan)

Hi,

Recently upgraded the CPU on my ageing Abit 1P-35 Pro (Rev. 2.00/BIOS v1.8 Beta) to an Intel Core 2 Duo 8600 (also upgraded my Graphics card, doubled my RAM to 8GB and fitted a new 2TB HDD).

Everything seemed fine, but the CPU is now overheating - hence sometimes has problems booting up into Windows, and so on (ie, gives me POST error code 9.8: "de-assert ATX power supply"). Right now, Speedfan software tells me that my CPU temperatures are 45C and 50C - that is, in the danger zone.

However, I was warned by the computer shop that my motherboard is faulty. Or as the invoice/fault details says: "The fan for the heatsink is Intel but the heatsink was third party - the two are incompatible - new heatsink required. Customer would like Arctic 11 Pro installed .... CPU fan not spinning, CPU overheating. Connected heatsink fan to sysfan header - fan spins and the system boots. CPU fan header and the AUX fan headers are faulty, most likely on the same channel".

Can I do anything about this using software like Speedfan - or Core Temp, Real Temp, HW Monitor, etc? Or is it just a question of biting the bullet and getting a new motherboard - ie, a completely new system, essentially, since I will have to get new RAM, CPU, etc. I've looked at Speedfan's settings, for example, but find it a bit baffling to be honest.

Here are my full tech specs: Windows 10 Pro & Windows 7 Ultimate (64-bit) \ Intel Core2 Duo E8600 (3.4ghz) \ Abit IP-35 Pro (Rev. 2.00/BIOS v1.8 Beta) \ 8gb Corsair PC2-6400 800mhz XMS (4 X 2) \ PNY GTX 9700 XLR8 OC 4GB \ Sound Blaster X-Fi Xtreme Gamer \ Corsair HX 620w PSU \ Hitachi CCTV DVR 7200rpm 64MB 2TB \ Sharkoon T9 Value \ Arctic Cooling Alpine 11 Pro \ Samsung Writemaster SH-S223Q \ Acer 24" X243H \ TP-Link TD-W8968

And advice would be appreciated,

Thanks,
DANNY

You probably can't get a new one, except perhaps a 5+ year old new-old-stock G41 chipset board with extremely limited FSB capability and only 4 SATA ports.

Used, the best and easiest overclocking board is based on G45 or P45 chipset, but it seems silly to buy one for a CPU worth $5. Especially as a used board may have problems like a dead fan header.

I don't see an issue with a dead fan header when there are five other ones to use. If you are dead set on controlling fan speeds with software instead of the BIOS, the only one that works with this board is Abit uGuru which only works in Windows XP. The company went out of business before they could update it for later Windows.
45C isn't hot (barely hotter than your forehead) and is a typical idle temperature for an overclocked Core 2. When you consider the Arctic Cooling Alpine 11 Pro is a $10 stock replacement heatsink, it's a great load temperature.

The error message is the board is not receiving a Power-good message from the PSU so in most cases, the motherboard should shut off

I have an IP35-Pro and can tell you that the fan setup in the BIOS is extraordinarily complicated, and has its own tab under the overclocking settings. The default minimum is either 8.0v or 30% PWM and that's just not enough to get some fans started, but you can easily adjust these values there but not using any software (the Abit has a fan control module that unfortunately has no driver for Windows 10 so shows up as unknown device in Device Manager). Fan headers can also die in such old boards but there are plenty of others.
