CPU temperature

[The Viking]

Here is how this story has evolved.

Thanks for all of your help. Here is how this story has evolved.

I got a call on my cell phone on Friday from the company that I had bought the computer from (http://www.tech.no/)
They had been discussing the thermal issue I had and concluded that I needed a larger heatsink. I was in the vicinity, so I said that I could pick it up later, which I did.

They could help me install the heatsink, because I had never done that before, but being cocky and all that, I naturally had to do it myself.

Attaching the new heatsink was as easy as taking candy from my little brother, but to detach the old one was really difficult. After a hard workout I finally manage to saw it of,, eh I mean get it of.

The old heatsink was a Molex and it was so tiny in comparison with the new heatsink I picked up at the store.
I have heard over and over that size doesn’t matter but this baby was 3 times the size, so the question would be; does it matter?

The new fan was from cooler Master (http://www.chillblast.com/reviews/dp5.htm)

SO after installing the new fan I fired up my pc and noticed that the temperature was 64 C!!! What was wrong here? Nothing apparently, because it steadily dropped downwards to 40 C. (I guess the thermal pad has to melt first in order to fill in those tiny gaps between the core and the heatsink?)

I then conducted a burn-in-test for 3 full hours using sisoft Sandra in order to really stress the system (http://www.sisoftware.co.uk/sandra)
The temperature was between 56-57 C after 10 minutes and it remained there during the rest of the test period. (When I conducted the same test with the Molex I reached 69 C!!)
After I turned of the burn-in-test the temperature immediately dropped to 50 C and then steadily decreased to 42 C. One thing that I have noticed is a 10 degrees increasing in the chipset temperature to nearly 40 C. This is probably due to the larger heat dissipation and because it’s much nearer the chipset than the Molex was.

A normal working temperature is now between 44 - 45 C and that is a 10-12 degrees improvement. I am sure I could degrease the temperature by enabling some of the extra fans I have in my case (4 fans actually) but I think the noise is too much with those on. I tried to improve the airflow bye arranging the cable neatly but I am NO way near the perfection of the ORIGAMI like cabling the Voodoo PC have, Check this awesome cabling here, it’s jaw dropping, http://voodoopc.com/home.htm

Anyways, do you guys think this is a normal ok temperature for a 1 GHz Intel CPU?

Thanks for all the help and feedback I have received, without it I would probably still be sitting with that Molex heatsink.

Best regards,

I'd say that those temps are perfect. My p3 667 varies between 48C and 63C. My chipset is always around 30C. As long as my cpu will be under 65C i consider this normal.

At the moment my CPU Temps Vary from 37 to 57 Degrees... Using a Stock Intel Heatsink with a 1 Ghz Celeron at 1.25 Ghz... so if you are pulling anywhere in that range I would say you are fine.

Yes this is normal, the thermal wax thats used must be heated up for it to function properly. Tho many of us remove that and either use regular Zinc oxide or more exotic heatsink compound like Arctic Silver (the best) for even better results.

Glad to see you got that thermal monster off your back!

BTW I finished the initial construction of my water cooling setup this weekend... deadly quiet and cool as a cucumber

Next is that special Geebe (minimal) case mod

Greebe, we want some pics of the new cooling setup!!!!
