I have an X2 4400+ and have decided to push my CPU a little bit further. As title suggests, its got a Big Typhoon sitting on top of it.

The CPU seems fine when idling - temperatures are 34-37C. After a bit of overclocking, I run the Super Pi 1M test to verify stability. The temperatures would just soar by about 24C bringing it to 55-58C and these X2s apparently have maximum recommended temperatures of 60-65C.

So I'm a little worried that I might damage my CPU, afterall I've only set the max vcore to about 1.5v. Other people have been stating their temperatures don't reach 50c when running these intense benchmarking programs...

I'm begininng to think that it's the Big Typhoon and its inability to dissipate heat quick enough? Though I may be wrong?

My idle temperatures seem fine, so I don't believe the HS needs re-seating. Would mounting a more powerful fan on the BT be a more adequate solution?

I've just checked this thread out:

and it seems the BT doesn't fair as well as other coolers.
 
The big typhoon is one of the best hsf you can get. It has been surpassed by the ninja and tower recently but it should still adequately cool your X2. Here are some hints for you to get the best out of your big typhoon:

1. Remove the fan, cut two slivers of sponge and stuff them in the two 'open' spaces on the heatsink(1 each side). This will force the maximum amount of air though the heatsink and not down the sides.

2. The big typhoon will only cool as good as the air circulating around it. Ensure it is being fed with fresh air (intake fan).

3. Replace the stock fan. This fan, while quiet is not the best performing and if you don't mind a little extra noise then invest in a 120mm fan that has a higher CFM count.

4. lap the base of the HSF. The base of the HSF was a big letdown for me as its got a very poor finish. I lapped mine to a mirror finish and it dropped 3c's. You don't need a mirror finish though, just make sure its flat and scratch free.

5. Its easy to get an uneven mount with screwdown type HSF, ensure that you tight both sides down EVENLY, i.e not one at a time. It may look like a good mount but if the pressure is one sided this will result in one core overheating.

Run your computer with the side panel of your case, if you see a big drop in temps then your typhoon is not getting the need amount of cool air to cool the cpu.
 
Thanks w3bbo. I will take each step at a time. I've ordered a new fan, the Silverstone FM121 coming in tomorrow or Tuesday - just to see how that goes. Hopefully that'll drop the temperatures a bit during load. I like the idea that I have more control on how fast the fan spins.

Also - I've heard above shoving some foam down the gaps and will most likely try that when I remove the stock fan. :)

Thanks for the solutions! :cool: :)

I've also tried running the PC without the side and the temperatures remain the same, I have a 120mm rear exhaust and a 120mm intake.
 
thanks for this info also mate, i will try the trick with the sponge, i find i have quite high idle temps but the full load temps are fairly good with my allendale chip (3150mhz @ 57 load)

I am also thinking of modding my case to add a side fan as this greatly reduces the temperature insode my sonata 2 :)

I've noticed the pretty rough finish on the base of this heatsink, how would I lap the base of this? Use some fine sand paper?

The big typhoon is a brilliant HSF!!

Basically says the Big Typhoon is on par with the Tuniq :eek: :eek: :eek: :eek:

I havent read the full thread but i saw the pretty pictures :D

Good thread. Well... my Silverstone FM121 fan has arrived today and this will replace the stock BT fan. I'm going to try reseating the heatsink, clear the dust out of Big Typhoon and apply some new AS5 and see how temperatures go... Will let anyone interested how it goes later....
