I'm planning to get a Barton XP2800+ cpu OEM, I have about £20 to spend- what's the best CPU fan and Heatsink I could get for it at this price?

After all, I like my games, meanibng stressful loads, and I don't want it overheating- I like an nice cool PC! :D

SHC is only a temporary measure however. In the long run it's only thermal conductivity that counts. SHC only absorbs quick changes in temperature.

Aluminium has a far higher heat capacity than copper does. So it takes a lot more heat to warm the entire mass up by one degree. Aluminium doesn't get as hot easily.

However because copper can conduct the heat away quicker from the die to the fan side of the heatsink then generally things can be kept as cool.

I live near a Shinetsu factory.

True story.

You should really. Isopropyl alcohol should bring this off.

Hum that's noy really possible unless you're really moronic, but you would be well advised to get rid of the thermal pad and put on some Artic Silver or Shin Etsu.

You know water cooling doesnt have to be expensive. Im looking at making my own water cooling set up for about £70, im just looking at cooling the cpu mind.

Well when you take off the stock heatsink there will undoubtedly be some remains of the thermal pad on the core, what you need is some isopropyl alcohol, or acetone free nail varnish remover and a lint free cloth to remove it. After you have removed it, it will have to be replaced by another thermal compund. Arctic silver 5 is about the best you can buy.

Hmmm, I'm considering getting a Jet 7 CPU Fan from SR.

I have very good recommendations from a friend, And the description says there are LED's on it aswell - would look good in a modded case.

Two reasons why I should, anyway. The Price is nothing, but i'm not hardcore enough to get Watercooling.



Having said that, when I pop the stock fan off the CPU, it'll probably leave half of it's pink thermal pad behind in a gooey mess, will it? If so, does it need to be repaired before I plop a Jet 7 on it? Because i've read that sometimes a faulty installation could occur where the heatsink isn't quite all touching the CPU.

Advice?

There seems to be a lot of apologizing in this thread between Turbo-lag-nuttah and biscuit fiend.

There could be any number of reasons for that. Have any of them specifically cited the aluminium fins as a reason? Can I have a link?

Im sorry, but ive read numerous articles which have shown that the aero 4 lite cools better than the aero 7+ (pure copper heatsink).
