In fact, it is the best performing TIM you can get today. Just don't use it on aluminum.

it stains copper as well

also to all the research ive done its NOT the best, but close

the funny thing is that it might actually work. but i would never do it.

Voila, your fancy heatsink is now your IHS, too, and the capacitors, which filter the power supply to the CPU will now be open to air, which will keep them cooler when you're overvolting the bejeezers outta the poor thing. Better yet, while you have everything apart, look up the part number printed on the top of the capacitor banks, find the spec sheet, and order replacements with a higher voltage tolerance. Come to think of it, if the stock IHS is already soldered to the CPU, it probably would be rather tricky. CPUs are connected to their circuit board using little balls all along the underside of the chip, meaning the slightest bump during removal of the IHS could create solder shorts all over the place. And if that happens, well, some few of us (the same ones with access to a reflow oven, probably), could possibly remove it and try to clean off all the solder, then reapply solder paste to each of the hundreds of tiny little solder pads, and then, -maybe- manage to realign the chip by hand before running it through the oven, but I imagine it would be pretty tough to do by hand. The solder paste they apply at the factory is probably microns thick, and applied by robots in a hermetically sealed room, or some such.

Sounds interesting. One day I'll get to this. My taxes are going to help me pay off about 4-5 credit cards, so spare change is in the horizon.

I don't see this working. I would say instead of soldering the HSF onto the CPU try to get pure silver or gold foil and place in between the 2. I can't imagine that a small piece of foil (silver or gold) can be that expensive. Just cut it to size.

A piece of foil will not conform to fill the microscopic gaps.

Well

there is a trick to redo solder in badly solder board and you use the over its a control environment an you can set the temperature you need

this trick use a oven at 385 degree to melt solder put it in the over you cpu should not suffer from heat shock and when the solder have melted just close the oven and wait for it to cold down

im not sure if a heat tube will support the prosses

i guess you can sandwich between cpu and the heatsink some solder

 

[Sinlok]

You'll have to try it with the CPU mounted. I don't know of a heatsink that doesn't cover the rentention latch.

 

[andrews2547]

if you are going to do this then make a video of you doing it and getting it to work then paste a link once you have uploaded it to youtube or what ever video sharing site you prefer to use

 

[hazarada]

assuming you are going to wreck any chance of warranty and put your cpu in high risk anyway - why not pop off the ihs all together, all it really does is add insulation. from there you could go nuts and do something like build a real IHS.

hollow out a cpu sized small copper block so it looks like a really short box
cast a plastic plate on the cpu covering the now exposed side except the dye and the copper box upside down along with it so the insides is airtight
make a tiny hole, drop in a tiny bit of water (just enough for the vapor to fill the insides) and take it to a boil, when there is no liquid left solder the hole shut and you are now in posession of the first ever heatpipe/ihs hybrid!

3 year old thread guys. Don't hold your breath.

 

[Ishinomori]

Talk about thread necro-ing... hope you guys aren't after a reply!

make your heatsink red hot make a small coil of silver soldier on top of cpu press red hot heatsink down on cpu should work in theory. i repeat theory! good luck

A 1000 degrees probably isnt so healthy for the cpu....

 

[Glancey]

OP clearly isn't going to do this, or if he has already.. he obviously isn't going to post how much of a catastrophic failure it was.. it's been like 3 years since the thread started. Move along.

 

[CircuitFreak]

I know it's a dead horse but the best way IMHO would probably be to fully lap the CPU and heat sink base with full copper exposed and get surface mount PCB solder that has the flux built into it spread on the CPU and HS and bake it together. Good luck ever getting it back off though. Someone has to be crazy enough to try this.

 

[inVain]

so, does the cpu dead already?

 

[davidjones25]

Computer chips traditionally run between 20C and 100C, solder wont melt at such cool temperatures. It takes a few hundred degrees to get solder to liquify.

 

[trev179]

Ahhh its 3 years old he obviously got in over his head

THHREEEAAAADDD NECRO!!!

well it is october...
