A7N8X reports CPU temp of 105 C

[Brian07]

I have just bought a brand new Athlon xp(t bred) to go along with my Asus Nforce 2 A7N8X. The board will post fine, but just kicks off before windows will load. In the Bios, I'm seeing the board report the CPU temp of over 100 C. I've reseated the heatsink and fan several times and I'm certain its making good contact. I can put an older Athlon 1700+ (t bird) in the board and it works just fine. Is there an issue with this board the the T Breds? All my t birds work fine, but so far I've used at 1700+ t bred and a 2100 t bred and both report incredibly high temps!

It sounds to me like the heatsink is reversed. Refer to this guide and note the illustrations Figure 7, Figure 13 and Figure 14. The CPU isn't going to reach 105C unless it's not getting good heat transfer to the heatsink, or else the heatsink's fan is not running or something. What heatsink are you using?

BTW, if you have a heatsink that comes disassembled, such as a Volcano 7+, be aware that the clip is asymmetrical and could be installed backwards too. Pressure point should be over the CPU core. On the A7N8X, that means the screwdriver-tip receptacle on a typical clip will be facing the top side of the board, the power-supply side. Ditto for the step in the base of the heatsink.

Using the above heat sink, with a fan. I've tried to make certain I have the heat sink on correctly, I've put many of these XP based systems together. I'll check again...

If the heatsink is assembled wrong, I woudn't think it would be working on the tbirds I have.

Thanks for the response!

Ok, I have an additional tip for the Thermalrights, because this happened to me with my Thermalright SK-7:

when you set the heatsink on the CPU, engage the non-screwdriver end of the clip, and then slide the heatsink as far to that end of the clip as it can go, so it's as far away from the top end of the CPU socket as possible. Otherwise, the situation illustrated in Figure 14 can occur.

I"ll give it a shot.

Thanks!
