A tricky situation....help pls

[Luke]

i have a HP slimline s3137c that i got from a person i who told me the power supply was bad which is i posted this thread: http://linustechtips.com/main/topic/173233-how-bad-of-an-idea-is-this/#entry2301613

 

I of course was not going to do all that unless i knew for sure the power supply was bad so i started by actually powering on the system and testing for myself. I managed to install windows on it but while i was doing so i noticed the fan was ramping up to 100% every now and then. When i got into windows the CPU fan would go to 100% way more frequently until it would eventually shut down after only a couple minutes.

 

So at this point it's pretty obvious that the processor is just overheating and shutting down the system but i tried again to make sure and yup the same thing happened. I put my hand on the heatsink but wtf? It's barely warm... I then put my finger on southbridge heatsink and holy mother of god that thing was hot. So i started by changing the thermal paste on both the CPU and southbridge and also stumbled across this post so i also changed the position of the heatsink to blow air across the southbridge as well:

I thought for sure this would fix the problem and after i booted into windows i thought it did but as soon as i started doing things like opening internet explorer and installing HWmonitor and installing windows updates etc the fan started going crazy but didn't shut down. Once i was able to see the temps HWmonitor was reporting around 50-60c idle and upwards of 100c when i was just doing basic stuff (core 2 hit 115c? ROFL).

 

So anyway i went into power setting and put it on power savings mode which limits the processor to 50% and now idle it's around 40c and "load" still makes the CPU fan ramp up to 100% with high temps but at least it's not shutting down?

 

Does anyone have any ideas? The only thing i can come up with is mounting a 120MM fan on the mesh of the side panel directly over the south bridgeand CPU heatsink and see if that helps but this piece of shit mobo has no 3-pin connectors LOL......It doesn't have any molex connectors either only two sata (one for the disk drive one for the HDD). I'm stumped, Do i just throw this piece of shit at the wall and call it a day?

I gtg to sleep but thanks to anyone that replies (if anyone does). =)

At least on my amd system the Southbridge gets ungodly hot.

And iirc the heatsink doesn't really get hot when the processor does.

But I still question the legitimacy of 115 c

Hmm i wonder what the shut off temp for a athlon X2 4800+ is then. I know HWmonitor can be silly but usually when it's wrong you can tell that it's wrong. In this case it's reading about 50c idle and feels pretty hot then when i start doing stuff and the fan starts spinning faster the temps on HWmonitor start rising then it shuts down at 100c +

 

I hope the temps are wrong though, lol.

I don't know, I've never pushed a system to that point.

I suspect the max temp is the typical amd 68c, but that's no shutdown temp though.

No CPU should ever get that hot under normal or even load operations.
Is it possible that the Heatsink (or cpu lid) is scratched at all? If either are scratched, you wont be making optimal contact, and will over heat like a biotch.

Check that out, and let me know.

There are little scratches but that came from me trying to scrape off the old thermal paste when i changed it and the CPU looked fine. The heat sink actually looks pretty good compared to other stock AM2 heat sinks. I mean it's smaller but it has copper heat pipes and a big copper surface for the CPU so idk. Maybe it's just defective?

Right, even the smallest scratches will cause it to not make proper contact, and get really hot.

Is it the CPU or the heatsink that is scratched?

The heat sink is scratched and the CPU is fine. The temps were 10x worse before i replaced the thermal paste and slightly scratched the heat sink though. The thermal paste fills micro-scratches anyway.

it could be the old thermal paste was a bad compound used by the factory?

And the thermal paste you put on was slightly better.
