Prescott Heat question...

post #1 of 11
Thread Starter 
I've got a question about a Prescott's heat:
I'm OCing for a friend, and after 20 seconds or so of Prime, his temps were up to 55*C, which was when I turned it off. Now, I don't plan on messing with the voltages, as it has a 20x multiplier and even 5MHz more FSB will net me 100MHz CPU speed. So anyway, will I be fine on the temps if I leave the voltage where it is, or does just a higher clock constitute for more heat? I didn't test the temps in Prime before OCing. Also, what are the max temps for Prescott chips? Finally, I'd like to get a simple heatpipe cooler for him instead of stock and use it with a squirt of my AS5. Would this be much better than stock:

Yes, it is a S478, and I don't want any CPU upgrade recommendations or any other coolers more than $10. He doesn't know much about PCs and won't want to spend $150 on a new CPU and $60 on a new cooler. Just like $10 is fine. Thanks.

better cooler.

and you can get up to 65*c, but it would be better to keep the load under 60*C for 24/7 operation.

That's a wonderful cooler and all, but it's 40 bucks. I specifically asked you not to go over $10. I wanted to know if I am fine with the temps as long as I don't increase the voltage (as in not having to worry because they will be the same as at stock) and if I picked the best cooler I possibly could for $10. No more.

The cooler for $10 would probably help with temps. The stock is just a big piece of aluminum on the top. The heatpipe design works a lot better. I would keep it under 60C full load for 24/7 running. Just see how far you can go with OCing at the volts you have now.

After you see the new temps when he gets the new cooler, consider raising volts for a little more OCing. Ohh and remember that Prescotts love volts and run hotter then most chips.

What I'm saying is: His PC doesn't overheat (obviously) at stock. If I leave the voltages the same, will his PC have the same temps no matter what clocks I use? Yes or no, please. I will not change voltages because his equipment is relatively old and I don't want to break anything. I don't know if his Mobo even supports voltage changes.

voltage increase is the biggest source of heat obviously, mine runs the same temp at 3.0ghz or 3.85, since i dont need to up the voltage.
as for dropping temps under 10$... all i can suggest is maybe another case fan or 2, some cable management, and a tube of AS5

Ran my Prescott 24/7 for months, sat at 71 on speedfan whenever I monitored it, you should be fine. 55C is not bad at all. Arctic Silver 5 will help you in the 2C to 5C ranges as reported. You may not need to even change the cooler. Cable management is free as stated above.

Prescotts can take that much heat but 55 is a good place to stop. Prescotts also have thermal throttling and unless you disable it in the bios they will insert idle clock cycles to cool the chip at around 65c. Good aftermarket cooling air or water will keep them under 50c.

No, his PC will not have the same temps no matter what it is clocked at. If you do any OCing on a PC, you will raise the temps. Obviously raising the volts would do more then raising the clock speeds, but they both will raise temps.
