How to put back the IHS on a CPU after removing it?

[suraswami]

I got a A64 3400 CPU here at TPU. IHS was removed for a reason and now I wanted to put it back and use it with a regular cooler. When I put it back the core doesn't touch the IHS at all. I verified this by putting a drop of thermal paste and nothing was sticking on the IHS interior when I put it on. I tried to squeeze using the cooler but that pressure is not enough. The machine starts and after a sec shuts off.

What can I do to fix this problem.

The CPU works if I don't use the IHS. I have to use a different cooler and do some alterations. The cooler is also tall and huge. But the board/pc/case I wanted it to go into does not have that much room to accomodate this Cooler. I have to go with a regular cooler.

Other option would be to put this cooler.

This is something similar to the Zalmans. I guess I have to remove the mobo to put this in.

Please advise.

sand down the bottom of the IHS until it touches the core again

I removed all the rubbery sticky thing on the ihs bottom and it makes little contact but not yet there. How do I remove it from the CPU? If I remove that I will get some more contact.

well it will allow it to be closer.... Rub it off gently, and then when you re-apply the IHS use some thermal sticky goop around the edges and then put some more on the ish over the main point.

two thoughts here:

1 - are you sure the circuit board hasn't warped from IHS from it not being there to properly support it?

2 - maybe a layer of ceramic thermal material will fill in the gap?

EDIT - i thought that rubbery sticky stuff prevented things touching and shorting out stuff?

I did number 2, but no effect.

The CPU is in good condition.

Can I use the MSI mobile pad instead?

The description says "Support AMD mobile CPU up to 40W heat transition design". The 3400 is a 67w cpu. And I will overclock a little. Will the mobile pad melt?

Sand HS till it touches the core?

cover that CPU up there are children here.

One is you. Where are others?

Just look around you will find many.

you need to sand it down (i sanded, you may want to do something else) all the black stuff off the heatspreader AND the CPU itself.

once thats off, make sure it has contact, and super glue it (around the outside, not the inside)

Personally, i find the old zalman 7000-Cu is the best bet for an naked A64. Fairy small, and since its screw adjustable it does fine.

Thanks. I cleaned the inner edges of the ihs, but scared to clean the cpu packing. I will try to peel off. But that rubbery thing on the packing acts like a cushion when I keep a big cooler on the core.

The above cooler is same as Zalman but from Ultra. Same type of screws etc.

Wanted to buy that CPU for $15 but ended up buying for $30 . No big deal I will spend another $20 for the cooler if that works properly I will be happy. Only thing is Full copper ThermalTake Silent boost and a Gigabyte heatpipe cooler will be waste of money

Just whinning

I did and it worked. I didn't put anything on the IHS to stick to the CPU packing, but put just a small drop of AS5. Put the IHS, wiggled a bit. Put AS5 on the IHS and put the Heatsink. Turned on everything is fine. Overclocked slightly from 2.4 to 2.65. Temps seem to be good. Idle @1.44v 42/44C and load 49/50C.

Thanks all for the suggestions.

congrats on getting it to work, my venice 3000+ was too much of a pain to get it on (glue made it higher, so it didnt work so well) so i just left it naked.

I preferred it to be naked as I can go higher with less voltage, but unfortunately none of the coolers (except the big and tall Titan) were compatible with the naked CPU. The Titan was huge and will not fit in my Avanix D-vine case. That is the reason I was struggling with the IHS.

Thanks.
