Do KT266A chipsets just run CPU's hot?

[Abzstrak]

I've tried everything I know of to cool off my wifes system... but its just hot. Its an Asus A7V266-E with a 2600+ on it, using a Volcano 12 with an air induction tube pulling in room temp air. The fan at full speed is like 73CFM and the damn cpu stays around 52C idle, 60C under load. I have it at 1.65V, and would try a lower voltage, but the motherboard doesn't support it.

She also has a 120mm fan pulling air into the case, and two 80's for exhaust plus the 80 in the enermax power supply.

There aren't any stability problems, but I'd really like it cooler, if anything just to slow down that stupid fan (obviously its alittle loud right now). I've tried downloading and using wcredit and turing on the HLT stuff (I've read its disabled on this chipset) but it didn't have an affect on temps.

anyone have an idea? otherwise I thinks I'm just going to look at an nforce2 motherboard.

What is the case temp? I am not familiar with the efficiency of a Volcano 12, but a decent heatsink should be able to keep the CPU within 10 C of the case temp. You may also want to reinstall the heatsink, just to be sure it is making good contact with the core. Are you using Arctic Silver or an equivalent? Another thing to try is to run with the case open. If the temps drop then you have a case cooling problem.
A long time ago I had a customer who got a AMD K6 that would always run hot. It turned out to be a defective processor.

My new MSI KT2 Combo doesn't seem to drive its CPU too hot. As another here said, perhaps your CPU is out of spec re. internal resistance. If it's a retail CPU, you may want to check with AMD about it once you've done the HS reseating excercise to no avail.
. Some of the HS pads that are out there require a pretty hot initial temp so that they melt and fill the gaps properly - I've read where you're supposed to leave the CPU fan disconnected for a short time so the proper temp is reached. If you leave out that step, it wouldn't be unusual for it to run hot. That's another reason I don't like the thermal pads - who wants to have to use their CPU as a melting device? It's Arctic Silver or similar goop for me!
..bh.

I don't think the 266A-era boards read from the thermal diode, do they? Maybe its just using a socket thermistor and it is not a very accurate one. I had an A7V that said my old 1.33Tbird idled at 85C! Course using another temp probe said it was more like 45C. have you checked with a temp probe that is not using the mobo's sensor?

i know my kt133a is hot enoughf to burn. i would think the kt266a would to. but my chipset has no fan. well my mobos lowest vcore is 1.66v i leave it a stock and it runs it a 1.55, odd have you tryed stock.

I've just been using Asus Probe to check, I guess I'll try motherboard monitor to check the diode.

and yes, its seated well... I've tried three different cpu's in this thing, all with the same temps. I use AS5 (yes I gave it a few days to set up) and it runs the same temps with the side off the case, which is why I'm starting to think the stupid motherboard just runs hot.... but maybe its just not a good reading.

Well, I use an Abit KR7A-Raid and my temps are pretty good, 53C load for the cpu and 35C load for the case. I only use 3 fans, all NMB B19's that have pretty low airflow. One is in the front hard drive rack of my Chieftec Dragon (Antec SX1030). Another is in my power supply, which does not really help the heatsink. The last is on my Thermalright SLK-800. I would recommend getting a better heatsink. I may be biased, but traditionally they are not too highly regarded.

uhm, yea..... got the same volcano 12 on my overclocked barton core at 2500MHz @ 1.825V its at 36C idle and 43C under load. Same cooling setup as my wifes (air duct), but on a A7N8X Deluxe.

Volcano 12 really is a good heatsink, if your not familiar with it you should look it up.

 

[PowerMac4Ever]

Sounds like a bad diodr/thermistor. If your CPU was really running that hot, chances are your computer would be locking up all the time. It looks like you have adequate cooling and your system is running stable.. I'd say you have nothing to worry about.

 

[Abzstrak]

ran motherboard monitor and got the same temps.

So I stuck the thermal diode on the volcano 12's fan and stuck it onto the bottom of the cpu. The thing is suppose to run at 5500rpm at 55C or higher, and its spinning at 5400 rpm at idle, and 5800+ rpm under use, so I think that my temp readings are correct.

so I underclocked the cpu to 1.5GHz and it runs about 4C cooler (not much eh?)... I can't drop the voltage because its at the lowest that the motherboard supports. While this as been a very trustworthy motherboard, I think its time to upgrade it.

Actually they do.
