Lapping vs. IHS Removal - Page 2

You guys are making me want to take the IHS off it Actually, I probably do it to my Venice after I get my beloved Sandy just to see how it turns out

I lapped my IHS, though, and it gave me good results, about 3C drop. Plus, since i had removed my IHS i got to replace the crap that they had in between for stock (they missed like half of the damn core). The IHS was also very concave, as was the stock HSF (took me about 3 hours to get it flat).
It is exactly as you have surmised. That can be solved by grinding down the retaining bracket mounts, preferably when not mounted on the MoBo. Perhaps you already have that on your "To Do" list...

Dockery, if you don't mind removing and re-seating your HSF multiple times, consider just lapping the HSF and see what kind of results you get. If you're not satisfied then Lap the Core... and then remove the IHS if you still are not happy. Just remember, Thermal transfer is based on the following:

1) Mass to absorb thermal output.
2) Airflow to remove the thermal output from the mass
3) Efficient thermal transfer accross mated surfaces.
4) The "flatness" of the surfaces.
5) Pressure.

Hmm... Well i'm not sure what grinding the bracket would do. And are you saying that there is a void gap between the CPU and HS base? The HS's copper base sits directly on the CPU. My HS is the Scythe Ninja. What part of the bracket do you grind down, if this is the problem??

I don't wanna jack Dockery's thread....

...but this does conern him/her also. When you remove the IHS you are removing a portion of the spacing. The HSF bracket is designed to meet flush with the mounting bracket (in every HSF that I have used - w/o mods ). The removed space must be compensated for on the bracket. A Dremel and a grinding wheel will do the job. You must make sure that the posts are taken down equally, the pressure also needs to be even.
Please remove the bracket from the MoBo prior to attempting this. Power tools have a tendency to skip...

In short, yes. You have a gap that is not allowing efficient thermal transfer.



... I see what you mean the bracket is a clip...? Maybe start a new thread asking this question.

I am indeed a him, and don't be concerned about jacking the thread! Thanks for all the information

I will probably just lap the IHS and the heatisnk both. It sounds a lot easier and I'm not going to be pushing my processor very hard so the temperature difference will probably be negligible for me.

My bracket is that black one. The HS is the Scythe Ninja, but the HS already directly sits on the CPU (the only part where the HS touches the bracket is to clip).

In your situation some spacing needs to be added. You could try taking high temp tape, neatly cutting small rectangles (4mm x 7mm) and "stack-tape" them to one of the surfaces (on all 4 points of pressure) that make contact and "draw" the components together. In essence you will be building up the area to compensate for the lowered HSF.

just to temp you some more....

and once you clean that gross thermal paste off that AMD uses the core shines like the sun
