Do colder PCS run faster than hot pcs?

Iv always been told you get more performance if your pc runs cooler. I know if your your pc runs cooler it will last longer but does it really effect the performance?
 
I really don't think temperature affects performance. You will usually be able to overclock to higher speeds the cooler the hardware you are clocking is, maybe this is what they meant?!

The only way I can think of that would make this be true would be processor throttling, but that's just a safety feature.
 
Processor performance is fairly rigidly fixed to clock speed. It's possible that they make mistakes, catch the error and rectify it, in which case cooler will mean fewer errors and a slight net speed increase. I'm guessing there though.

Cooler processors suffer less from leak current and so use less electricity. Oddly as a result they also throw out less waste heat, so are easier to keep cold.

The main benefit is overclocking, where if "error correcting code" of some sort exists it's likely working overtime, leak currents are a bit ridiculous and power draw goes up sharpish, thus killing both previous arguments for keeping it cold.

Anyone know if processors make and correct mistakes. ecc ram style or otherwise?

Yes they do.

Intel's Nehalem EX To Gain Error Correction

Intel Upgrades Hardware

angry tapir writes "Intel's eight-core Nehalem EX server processor will include a technology derived from its high-end Itanium chips that helps to reduce data corruption and ensure reliable server performance. The processor will include an error correction feature called MCA Recovery, which will detect and fix errors that could otherwise cause systems to crash — it will be able to detect system errors originating in the CPU or system memory and work with the operating system to correct them."
 
I also read that as the Itanium chips and this upcoming one feature error correction, and the rest don't. The links given me a few things to look up though, cheers guys.

Thats a server CPU so in 99% of people on here the answer will be no :)

He just said processors. So therefore my answer.;) If they can do it therefore other cpus could have errors ;ecc style etc. and also it's a possibility to have error correction as it's being done regardless of whether it's a server chip or not- shows the capability is there.
