CPU Fan

[Dave Miller]

What should I consider when choosing a new CPU fan?

My CPU fan is starting to make a scratching noise, and I'm going to replace it before it breaks and damages the CPU.

What seperates a good CPU fan from a bad one? Are the more expensive CPU fans worth the extra cost? Who makes the best CPU fans?

Thanks!

Dave

You are definitely correct to replace the CPU fan at any sign of trouble. CPU fans are cheap, CPU's are expensive!

1. A good sized heat sink.
2. A fan and heat sink combination that will fit your PC case - a lot of PC cases are very cramped.
3. BTU rating: How much heat can the CPU fan dissipate?
4. MTFB: How long should this CPU fan run before failing -- on average.
5. Quietness: How annoying is this fan?
6. Fan speed. Is it adjustable?
7. Bearings. A fan which uses bearings will last longer and be more reliable.

Don't forget these other items:

1. Thermal paste: Air space between the CPU and the heat sink will cause heat build up.
2. Case cooling: Keeping the CPU cool starts with a reasonable case temperature.

The CPU fan manufacturer I would recommend is Cool Max Technology.

Get a good brand to start with. Look for reviews online, dont buy anything without reading reviews, it can be fatal for the CPU.
Nice list Will, that should be a sticky!
