Resell value going to kind of blow thou ...

Take note that the Athlon XP has little rubber feet to help support the weight of the heatsink. If you're worried about crushing the die of an IHS-removed CPU, then use find an old AMD CPU re-use those rubber feet on your new IHS-removed CPU to help support the heatsink's weight. thumb.gif

korrrhonen, or better known as SF3DOC, the Finnish extreme overclocker delidded his IB..

http://murobbs.plaza.fi/1708625462-post736.html
In his own forum with the two pictures:
"I changed the paste between the IHS and die, but the IHS HAS to be in place, or else the brittle processor pcb does not make proper contact with the socket pins. This operation helped a little, now it doesn't throttle so easily near 4.9Ghz. I got +50Mhz, so there is NO BENEFIT. So, DO NOT destroy your cpu's."
And in MuroBBS he posted:
"Like you might have guess, the IHS removal or changing TIM didn't help.
*link to his forum*
The overheating near 5Ghz is just simply because of that architecture, it is not because the IHS and die would have a bad contact. The temperature jumped to 105*C just like before.
So all it needs is extreme cooling and presto the clock scaling continues."

korrrhonen, if you happen to read this, thank you very much for doing that and hopefully this gets out more so people don't go and delid their IB's just for nothing. Huge thumbs up to you thumb.gif

Unless he changed the mounting of that water block, that exercise was futile. The XT is designed to put a pre-set amount of pressure on a CPU with an IHS. Removing that changed the potential pressure to be applied. The CPU wouldn't make proper contact because the pressure applied by the XT on the CPU isn't even strong enough to hold it in.

Regardless, no one is saying that de-lidding the CPU will drastically decrease temperatures. The whole point is that Intel went with TIM and not solder, the latter of which would result in better temperatures because of the much higher thermal conductivity of solder between the die and IHS.

Steel cap? Really? I find it hard to believe it's steel. Try aluminum.

The IHS is made of nickel-plated copper. Hah, I now see VR-zone said steel. Just for the record, we never said that - and wouldn't have, because it's quite inaccurate.

Mostly copper, actually.

actually shammy@asus states that changing the TIM to something thicker improves the thermals as would thinning out the IHS feet. By how much and what benefits isnt clear just yet.

Cutting the IHS completely would improve it most.

Chat InformationYou are now chatting with 'Adolfo'

Adolfo: Hello. Thank you for using the Intel Customer Chat Support service. We are glad to be of service. How may I help you?

Bloke: Hi, I have a question regarding the announced Ivy Bridge processors as a potential buyer (currently using AMD processor system) and processor in question is the i7 3770K. I have read online through reviews that the ivy bridge processor is using thermal paste instead of solder as a thermal bridge between the processor die and the integrated heatsink. This is being blamed for higher temperatures. Can you confirm if this is true and if the ivy bridge processor will continue to have thermal paste used when launched instead of solder as the thermal interface material? Also I have seen reviews that sandybridge processors ie 2600/2700K used solder as the interface material which resulted in much better temperatures.

Adolfo: All Intel(R) processors have used Thermal Interface Material the entire time and this has not changed; furthermore, the processor is not yet released. In case you would like to get more information about the processor, feel free to refer to:

Adolfo: http://ark.intel.com/products/65523/Intel-Core-i7-3770K-Processor-(8M-Cache-up-to-3_90-GHz )
