Hot Heat Sink!!!! which in this case isn't good!!!

[Pangolin]

hi,

I got a swiftech MCX-462 about a week ago. I have an athlon XP 1800+ on an Epox 8K3A+ mobo in a coolermaster atc-210 and the fan is a DELTA 68.5CFM. With the side panel off the cpu temperature as reported in the bios is 42 degrees and then with the case on, the temperature rises to 47-49 degrees. I want to overclock this machine, but am slightly worried about doing so as the temerature couldrise even more and damage stuff.

The question is... should the cpu be running at this high temperature? is the temperature reading correct (i've heard some dodgy things about the diode under the chip...)? should i send it back? ok so that's nore than one question....

Thanks for any help that there might be

did u use artic Silver? or the thermal Pad...those temps are perfectly fine but with that HSF... u should be lower, remove it, put on some artic silver..and BY THE WAY... i am not sure if on the switech, the fan should blow or suck...find that out, that could be your reason.. 🙂

Sounds like case ventilation problem.

Any case with decent air flow-through should run cooler with the case closed than open.

I would expect cpu-idle temps in the 30s with that heatsink/fan combo. That's what I get with Alpha 8045U in Inwin 1030 case, and you should expect better with your higher-flow fan on the Swiftech.

Hope this helps!

I am using arctic 3 paste. In some reviews the temp has been as low as 30 degrees!!

This is why I am worrying..........

to me, it sounds like there isn't a good contact with the core. remount the heatsink with fresh AS3, and then take it off again. if you have a nice little rectangle of paste on the bottom of the heatsink then you have a good contact.

A very thin layer is all that you need.

Don't slather it on like peanut on toast! 😉
