1.2 GHz running much hotter on new asus a7v133 mobo?

[shaggyfl]

I just moved my AMD 1.2 GHz t-bird from an ECS 7KVMA Mobo to an ASUS A7V133 mobo. The problem I am having is the CPU temp is running about 60 to 64 C and when it was on the ECS mobo it never ran hotter then 54 C (this was overclocked to 1.35 Ghz and running a stress test for about 2 hours). I have not overclocked it yet on ASUS. I have the same thermal take volcano II hs that I used on the ECS. The only thing I noticed different is the core voltage is a little higher on the asus. Anyone have any idea?

Thanks

It's probably a combination of a few things...

1. Check you HSF, make sure it's properly seated on the core.
2. Re-lap your HSF base, clean all the gunk off the core of your chip and re-apply thermal paste or AS.
3. The voltage probably has a little bit to do with it, but not much I am guessing.

Joe (or was it Ed?) posted a little blip on the front page about how different HSF's perform differently on different motherboards because of socket positioning. (from Anandtech forums) I would guess that maybe with that new mobo, you should think about tweaking the airflow in your case.

It's also an established fact that the Volcano II's aren't the best HSF's either, especially for these heat furnaces we call Thunderbirds. I have a FOP32 on my AXIA-Y 1 GHz chip, and its nowhere near enough. It was fine for my Duron but now I've stepped up and I'm going to need a better HSF unit. I'm thinking of a SK6 or a Swiftech MC462, most likely.

It appears that different manufacturers calibrate their sensors differently. I don't remember where I saw the article but it states that different boards will report say 30C as possibly 27C or maybe 33C, depending on the brand. It states that Abit reports lower than actual temps, while ASUS, generally, will report temps higher than they actually are. This might be part of what you are experiencing.

The core voltage will be reported slightly higher on SiSoft Sandra and AsusProbe, others too I suppose.
What are you using to monitor the temp??
AsusProbe is noted to be high. On mine, MBM5 seems real close to the ribbon sensor, located next to the core.
