Hi, I want to buy a cpu that produce lessest heat. It can be any speed and brand, becase I want to buy cpu before buying the others stuff.

A 386SX-16 runs pretty cool. New stuff whether AMD or Intel is going to run pretty hot. Speed makes heat and you're stuck with that.

Someone will correct me if I'm wrong but P4's tend to run cooler at idle but have larger temp swings from idle to 100%.

AMD's tend to run hotter at idle but only increase a few degrees under load.

Good cooling and installation practices will keep cpu temps under control regardless of speed or brand.

Next?

Ya, a 386sx would be good for you. I think that VIA makes a CPU called a C3 (Class 3) @ about a 1Ghz that runs cool. But class 3 sucks and it's about as fast as a 386sx/.LOL

lessest heat? any speed? uh, how about a pentium 100mhz? sorry, I couldn't resist....

It really doesn't matter if you get an AMD or Pentium 4...they both produce approximately the same amount of heat...but the Pentium has thermal protection built in to the CPU, while the AMD's thermal protection is incorporated into the motherboard. If they're setup properly (i.e. good HSF, thermal paste or pad, good case cooling, etc), either one will work fine. Any horror stories that you hear or read about AMD CPUs overheating & burning out have nothing to do with the quality of the AMD CPU itself...it almost always has to do with the way the system was assembled

Well, there ya go. If you don't want the 386 do your homework, cross all the t's and dot all the i's. You'll be fine.

My recommendation would be P4 Celeron 2Ghz and higher. The 128KB cache keeps the CPU cool enough for office applications, i.e. Excel, WinWord macro writting and most non-engineering heavy usage.
They are inexpensive starts retail price of less than $70.

The coolest running, current, CPU I know of is the VIA C3, it will even run without a HSF, though not recommended. They don't run too bad, but it all depends on what kind of speed you need. If the C3 won't cut it, then I would follow Real_Cool's advice and go with a socket 478 Celeron. At least that way you can run DDR, possibly dual DDR, don't know how good that would be though.

Can I get into this act also.

LOL bit late but work calls first.

Spot on Skip, the p4 can have some wild temp swings that is for certain. Intel didnt desing the overgrown heat sink for no reason.

We all tend to bag AMD but the thing has a smaler temp variation than the p4.

But lets not forget the environment in which they live in has a greater impact than what we tend to think.

If you are worried about the computer heating up the room I suggest you get a laptop, a large 17" LCD display, Keyboard and a mouse. Performace and money wise its a stupid thing to do but it wont generate half as much heat as a "real" computer. It will allso ad a portability to your system.

Or you can go with 486 DX2 Its pretty cool...

Steam

I can sell you a 486 with 200$ Intrested? LOL

Thanx for all your suggestion. I am going to but a P4 cpu, but i want to keep the cpu heat as low as it can. Is using the Bio to turn down the spped of the cpu, going to make lesser heat?

Won't help much... Maybe with an athlon as you can drop the multiplier, but with an P4 being multiplier locked the only way to underclok is dropping the FSB and that will cut the performance too drasticly.

The real heat gain in OC'ing comes from the Vcore increase and not the performace increase.

The best bet is to buy a processor and leave it as it is. That will give you an optimum performace / heat ratio. The OEM P4 heatsink does an adequte job cooling of the processor if not overcloaked.

The thing you can do is using a softwarecooling program like CPU IDLE.

There really is no way to have an effective new computer without it making heat.

One way of decreasing the heat generated is to buy an old videocard that wont produce as much heat. Of course that will drop the performance a great deal. But as said many times before, Speed = Heat. No way over or around. Sorry.

Just buy a water cooling sytem and any cpu. The water coling will make it run at like 30C (86F)

Listen to Steam. Put it together and run it at stock speeds/voltages.

Hello bctps55. I was wondering what you intend to use this O'Ced system for? If it's for gaming or cgi/rendering, then I'd suggets the new P4-C processors.

I just recently put together a system using the P4 2.4C proc on an Asus P4P800 Delux mobo with 1GB GEiL DDR3200, and am currently running it (have been for 6 weeks without a hiccup) at 3.2GHz with a DDR clock set at 5/4 (equivalent to an 853 MHz FSB) and a GeForce FX 5600 Ultra O'Ced about 15%. The CPU temp went up about 3 degrees Celcius, the ambient motherboard temperature increased by 2 degrees Celcius, and 5600 Ultra's GPU temp went up a total of 3 degrees Celcius as well.

All in all, under load the exhaust air temperature increase was ~3 degrees Celcius (total 82 degrees Farenheit at the sensor). Runs 3DMax5.1 like a champ, Poser 5 renders in seconds and games scream. All in all, system cost was ~$1250.00, including 120GB S-ATA HDD, CD-R/W and DVD-ROM. I do, however, have an Antec Plus1080 AMG case, with 5 Antec quiet 36cfm fans in it. Hope this helps.

55's looking for a no hassle machine that will run as fast as possible...nothing wrong with that.

Also nothing wrong with your machine. You did a good job there.

55, we had some fun with you here. You're making a good choice. Carefully put it together and enjoy.
