Freezing Heatsink Compound

[parki90]

Im trying to cool my cpu, would Freezing Heatsink Compound in a tube, then applying it to the CPU Help?
Knowing in theore; the compound would stay at a ambient tempeture once it wasn't frozen any more., or maybe freezing the heatsink.
Also if a cpu has a heat transfer pad, and i want to apply compound would i have to remove the pad?
Thanks

The freezing ideas are bizarre and removing the pad is likely to reduce the conduction from the cpu to the heatsink.

Just make sure the fins on the heatsink are not bloked with dust and the cpu, case and power supply fans are working properly. Endure the ventilation slots are not obstructed.

If you are still having problems then stop overclocking the cpu.

A very strange idea indeed!

if you want to cool your CPU more the only ways of doing it are to either increase the airflow other your current heatsink, fit a larger heatsink and fan or fit a cooling system that uses liquid rather than air to cool. playing about with your current heatsink in the ways you describe will at best make no difference and at worse make it less effective than it already is.

Thanks for answering my questions. i can't understand why my cpu is running so warm. its a intel 478 socket, im use too 775 sockets. is when i play games in full scrren mode thats when i worrie because i can not monitor the temp.

I have irradicated all dust and logs from the heatsink and surrounding the board. it still runns at 47'c idle to 66'c+

ive took the big fan from my 775-AM2 OC Freeze Heatsink and put it to the side of the heatsink in the tower. still no change really in temp?

You've not said what CPU it is, but if it's a socket478 celeron then that is well within the expected temperature for some models (some of the celerons run really hot!) if it's a P4 it is up at the top end of expected temperature.

presuming that the heatsink is making good contact with the CPU using either the supplied thermal pad or decent compound then you have either hit the effective limit of that heatsink and it's needs a larger one, or you need to be moving some of that hot air out from inside the case and get some cooler air in there to blow over the heatsink, in which case time to look at fitting a case fan or two.

Thanks again. It's a Pentium 4 2.5GHz

I have already two fans taking airflow out from the back, and two taking airflow in from the front.

Im going to try freezing the Heatsink. Ive carefully bagged the unit in a sandwich bag tighed it up and popped it into the freezer. in a couple of hours il install it and check the temp.
Its a little experement, which will work untill the frozen heatsink reaches ambient temp.
Hopefully il see tempretures below 37'c instead of 47'c-66'c.
Also the Heatsink is a coolMaster Full copper heatsink with fins and two copper pipes to "disepate the heat". (so i thought) 66'c with a Coolmaster copper heatsink doesnt seem to add up?

Result.. From a Thermol'meltdown temp of 66'c

Freeziing the compound and heatsink reduced the temp to 37'c idle and a peek of 51'c on full load.
All thanks to trail and error.
P.s---- I Kinda knew what to do to reduce the temp, pluss it would be my own fault if anything were to go wrong.. If you don't know what to do 'Don't Do It'
