Should I try a different brand of paste? Is it the connection between the heatsink and CPU or is it giving a faulty reading? When it was at 100C the heatsink was definitely not that hot to touch, considering 100C is boiling point for water it would've been around half that.


There were some early Brisbanes that had a faulty temp sensor, not sure if yours is one of them. Maybe the OPN will show if it is.

Have you confirmed that the heat sink makes good solid&even contact with the CPU core heat spreader. Could also try with lesser thermal paste, a very thin layer.

Do you have a shutdown temp set in BIOS? Just asking in case the shutdown was made through BIOS or the CPU itself.

Yes, the shut down temp is 80C. I've used barely enough to cover the CPU and it still got up to 77C before exiting the online poker game and the temp dropping immediately.

This only started a couple months ago out of the blue. Before this I was playing Battlefield 2 on the high settings for hours without problems. Now, flash games are making the CPU overheat...

Seen some bad thermal paste that "melts" away from the heat spreader, only leaving a transparent greasy layer which does not conduct heat, the thermal stuff flowed to the sides of the heat spreader after a while of hot temperatures. You can use OCCT to switftly test for heat while checking if any effects of your cooling measures.

Well the thermal paste I got was recommended to me by the older sales assistant at an electrical supplies store, so I guess it's decent stuff. I'm thinking my CPU is about to pack it in, and I've got my eye on a similar CPU for an upgrade - AMD Athlon 64 x2 6000+ 3GHZ Dual Core. It's second hand on ebay, the buyer assures me it runs well with no problems with overheating and comes with heatsink.

With my current mobo (Asus M2N-MX SE) would there be any problems using this CPU?

Having said that about the thermal paste, every time I've removed the heatsink the layer is always uneven, with some of the paste barely even on the CPU despite putting it there beforehand. What's OCCT?

Need to confirm if it actually is a thermal conductive paste or the opposite, both exist.

The layer should look even also after removing heat sink, check the retention bracket and the heat sink clips that they are able provide an even pressure upon locking lever.
This may also explain the temp difference you saw between cores.

For the X2 6000+, check whether it is a 125W tdp or 89W tdp model, if it is a 125W model, confirm your motherboard supports it, as some motherboards do not.

google OCCT (3.1.0).

I told the guy in the shop I needed thermal paste to go between a CPU and cooling fan, he chose it for me so I'm assuming it's the right stuff. Looks identical to the stuff I had to remove the first time.

Here's the results of OCCT... doesn't look great... the other core is almost identical. Also the CPU I was looking at is 125w, and you're right, my motherboard doesn't support this so thanks for the tip as you've just saved me both time and money (not to mention frustration).

I've reapplied thermal paste after this, I think I did a better job as the temp is idling at 47C (not running OCCT).

No, that is horrible, CPU temp skyrockets as soon as there is load. Sorry can't dig through the thread at the moment, but are the any setting re the fan in BIOS, smartfan, threshold etc.?

I've got the cool and quiet turned off and the fan always runs at it's max, which is about 3125 rpm.

I'm having the same core temp difference problem with my AMD Athlon X2 4200+. M/B is a Asus M3A. CoreTemp 0.99.5 shows a difference of roughly 10 degC between the two cores, both at 0 load and 100% load. I've just sent an email to AMD Australia regarding a warranty replacement. I'll let you know how it goes....

Yeah I'm getting the same difference between cores, although I checked the top of my CPU and it was made in 2005 apparently, so I think it's past warranty.

that date doesnt matter what matters is when you bought it


you warrenty starts from the day you bought it not from the day it was manufactured

and did you clean the thermal grease before applying it again?

I don't have a receipt, my girlfriend gave me the computer after buying a laptop at the start of the year and she's moved house twice since buying it, and she doesn't keep receipts... plus you can't login to the AMD support page to make a warranty claim anyway, I've tried over a dozen times and it doesn't work - another forum member has the same problem.

And yes, I've cleaned the thermal paste off each time I've applied a new layer.

I've disconnected the 2nd HD and put it back to the integrated video card to see if that helps. So far so good...

Answer Answer
Jaekus, I finally got through to registering from my office computer. But the form indicated my CPU was no longer covered by warranty. I called the phone number instead, and the rep was very helpful and honoured the warranty by phone. I returned the CPU, and got the new one back within a week. I'm monitoring with Core Temp and will see what happens. So far so good.

Hmmm, I might look into it soo, although the CPU is still operating at a lower temp, but that behaviour is unusual. Thanks :-)

I called instead, and was offered a replacement right away. Very helpful at their hand. I returned my bad CPU and the replacement one arrived a week later. I'm trying it out right now.

id bet money on this, disable auto shutdown and take a manual reading of your heatsink under 100% load see if its to hot to touch, if its not then guess what your temp sensor fried

I swapped CPUs for one my flatemate had in an old system sitting around (AMD Athlon 64 3200+) and guess what? No overheating. Ran OCCT for 15 minutes and it was pretty consistent at around 50-53C, spiked for once second at 54C. Ran the same test on the suspect CPU and after 5 minutes it was reading 57C and 46C on both cores and continuously rising. So I think I've found the problem. AMD have also contacted me via email, hopefully warranty is a possibility even though I don't have any proof of purchase details.

Just to update, looks like I can get warranty after all, as follows:

-----------------------

Hi Jacob,

2005 is actually the technology licensing/release year of AMD dual core processors.

Your processor was manufactured on 19/11/07.

The processor has the date code indicated and is found on the 2nd line marked on the processor

0745BPBW - (2007 Work Week 45)

Regards
Desmond

Ace. I'm sending it first thing tomorrow, as soon as I can find an antistatic bag...
