Help with Thermal Paste on My Copper TBird shim

[TRD]

Hi.... Im using Artic Siler thermal grease and have a copper shim to put between my GlobalWin FOP32 and my TBird 1000. My question is..... how should I apply the grease? should it only go on the CPUs chip????? Or do I need to put any on either side of the shim's surface?

Thanks in advance to all who offer ideas.

Thermal paste on cpu core only. thermal paste on shim(on either side) is more likely to increase cpu core temp than to decrease it.

only apply a thin coating to the cpu.
ideally you should not spread the arctic silver with your bare finger pulp as it leads to contamination of the paste with oil & skin flakes decreasing its overall efficiency.
ensure both mating surfaces are clean using something like rubbing alcohol or acetone before assembly.
good luck

copper shim is supper suck. i just throught it allway. well i have very nice copper shim with four hole on it.
i use it with taisol 749... modle with delta 30cfm and orginal taisol fan mount it on side of the taisol hsf.(i also use it with artic silver too) 1 gig week1 2001 with abit KT7A-RAID. no over clock. after first boot. my cpu tem is supper hight 70c within 30 seconds it drop to 30cfour minute later go down to 28c. i cannot overclock it with coppershim. every time i try it overclock it .it won't boot cos of heat problem. i take the copper shim out and set it to 9x133=1.2 it boot up just like a magic

HMMMM.... I seem to get alot of different info thru the web. What I did was using a rubber glove spread some Arctic Siler on the CPU chip itself, and then placed to Copper shim (custom fit for TBIRD) between theprocessor and the global Win FOP 32 HSF..... I seem to boot at about 95 deg F and it will drop to 89 deg F... after a while on tinkering around I have seen it go to between 105 and 109 deg F. I know the Voodoo 5500 AGP is giving off alot of heat but it seems high of a tem,p. My core voltage is set at 180.

By the way....I am running the case with the sides off as Im still assembling the system,.

Again thanks for all the info, it helps alot.

Well whats the copper shim for. The more thermal interfaces you have the poorer the heat conduction. Loose the shim and put some thermal paste between the CPU and the heatsink. If you loose the shim then you have cut your thermal interfaces in half. If you want to get really high class get you a small sheet of indium. It will conform to the shape of the heatsink and CPU and you won't need any paste.

Heat transfer 101.

Perry,

The shim doesn't contact or interfere with the Primary heatpathway.

Mikewarrior's correct, the shim is only used to distribute the weight and balance of the heatsink so as not to break/crack/chip the core of the CPU.

According to most overclocking sites the copper shim is an ideal heat transfer mechanism to pull heat from the CPU to the HSF. An as mentioned above, it doesnt come into any contact with the primary heat pathway of the CPU. It is cut to slip over the procesor.

I did as much research as I could prior to my purchase and seemed short of Peltiers, Water Cooling, or Alphas...... this was an ideal setup..... I guess from what Im hearing my temperature isnt sooo bad after all.

I don't know where you did your research but the copper shim will not add to your cooling !!. It will also NOT distribute weight. Its only function is to prevent the hsf rocking on the core during assembly. No TBIRD or Duron will crack when the 12-20 lbs of clip pressure is applied perpendicular to the core. When assembled, the shim should NOT touch the bottom of the hsf. Overclockers has a great article on shims, but they only test them in a sub-ambient environmment, the results can't be compared with ambient air. In sub-ambient conditions, the shim INCREASED temperatures in most cases.
