if i run the cpu without the heatspreader will it effect anything?
1. will it hurt it (assuming i use AS5)?
2. will it run cooler?
 
If you run the CPU without the heatsink its going to get extremely hot and shut down on you. AS5 only trasfers heat from the CPU to the heatsink, so it wont do crap.

Oh, i was thinking you were being a noob and thought you wanted to take the heatsink off :P

The heatspreader transfers the heat from that small area to a larger area, if you take that off then there will be less room for the heat to dissipate.

I would not take that off, you may damage it as well.
 
yea, i guess...
but if i can get the heat transfer better and lower the temps by like 5C then it's worth it.
also, the heatsink transfers heat from a small area to a large area too :) not just the heat spreader.
 
i know it does, but the area of contact if you remove the heatspreader would be much smaller, and you would probably lose any gain you would have made by having better thermal paste.
 
Removing the IHS should theoreticly reduce temps. Think about it, the IHS is just another layer for heat to travel through before it gets disapated on the HSF. If you remove it, your getting direct core contact, and the heat doesnt have to travel through another layer of resistence. Lots of people remove there IHS and get lower temps. Just beware unless your HSF is a bolt on design, you will need to modify the mounting brackets so that the HSF retains good contact.

might find that useful as a guide to "de-lidding" and Athlon 64. Seems that its a process to be wary of becuase of the obvious possible damage to your CPU when trying to remove the heat spreader.

But it seems people have seen a significant decrease it temps once this is done.

Just remember that your Heatsink may need to be altered to make good contact though as the contact point will be ever so slightly lower down with the heatspreader removed

Thermal pastes are used becouse of the little holes on the heatsink and heatspreaders (on CPU's) so heat can be 100% transfered to the heatsink, if both of these surfaces were perfectly flat (heatsink and heatspreader) there would be no need for thermal paste. I hope you guys understand. (I know some of you will)
 
Someone over at XS did this and got much better temps- more that a couple of degrees i think-

there is great danger in taking it off though, but a razor blade is the tool of choise.
 
i can see temps decreasing a lot if you do it right... at the moment the core is actually a fair bit away from the heatsink... air gaps are a buger for heat, if you strip it down and have full contact with the physical core, thermal transfer is soo much greatly increased that the reduced surface area will not matter all that much...

There has to be a certain amount of pressure on the CPU, if you could get a thin copper plate (2mm) that would be between the heatsink and the CPU it would be great. Copper is a great material for conducting heat, which means it can pull the heat off of your CPU faster than aluminum.

it would be even better if it were gold as its the best conductor, but sadly that'll cost hundreds of $

Too bad you're wrong. Golds thermal conductivity is 318 W/(m·K), meanwhile Coppers thermal conductivity is 401 W/(m·K).
 
i wouldent need to do anything to my XP-120, that thing holds on tighter then a.... well... it holds tightly... very tightly to the mobo, wouldent budge if i tried, lol

i can see where your coming from there but you are wrong, gold is a good conductor of electrical signals, which i think is what you were thinking of. For conduction of thermal energy, copper is the best price:performance ratio... im not entirely sure what beats copper... i'll go check

I know that, but from what he said it sounded like he wanted to remove the heatspreader, and only put AS5 on it.

Silver is an even better conductor according to my chemisty data book (Revising for exams :()

Silver is down here as 4.29 W/cmK
