S939 A64 IHS Removal

Nothing wrong with that idle temp, it's the load temps that count though.

If temps shoot up when you use Prime it would point to the contact not being good enough.

Not sure on the GT, on the Vapo Clamshell all you need to do is push it back up the flexible tubing to get in the back.

Sounds like it's making good contact though, what were you're load temps before you removed it?

they were at MOST 48, but usually around 47ish. idle temps were slightly lower too. could it be air flow in the case? - but if it were that then surely the temps would be the same.

*sniff* is my zalman faulty?

thanks

Nah, that sounds ok, just sounds as if the IHS was making good contact in the first place. The slight difference in temps is probably down to slightly different ambient temps.

what is the max temp i should let it get to?

I've started using this program here. It appears to give a slightly more conservative figure than the ones found on AMDs website, but given the inaccuracies in temperature measurement that can only be good thing.

i took my ihs off sucessfully my optie 148 about a month ago, then a week later blew the chip

Ouch, what happened - too much voltage?

You need to apply a lot of pressure I think, how much of a gap do you have between the IHS and the PCB?

Next to no gap. Will the pressure of my freezer pro not be enough? Pretty sure i have made an arse of it anyway

Should do I would have thought, was this the one that was hot? Maybe the IHS isn't flat or something. There's not that much TIM on the inside to be honest.

This is another one lol Im going to take it off again and have a look. What do you think to using a ShinEtsu thermal pad good idea, bad idea?

I would avoid a pad to be honest. Try it with AS5 and put it under something heavy without the sealant and see if it makes good contact.

Are you using a cold plate between the TEC and IHS?

I will be when I re-assemble it all tomorrow

I used to use liquid tape over the top of small chips next to the core but as far as I can tell it not necessary. If you've got a cold plate then it might drop you temps a degree or two or more if you're lucky as the IHS is just more metal in the way between the chip and the cooler.

Cache chip?

The cache is on the core, not sure what they do, but if you lose one sometimes they work, sometimes they don't.

Jokester · 18 Apr 2006 at 22:40

What cooler are you using with it?

Jokester

Jokester · 18 Apr 2006 at 22:56

Nah, that should work fine, is there any obvious damage to the core?

I have a feeling it was mentioned earlier in this thread. (Or maybe it was on DFI-Street)

Why not try cutting the rubber seal with some sewing thread or something? It would take a while to do but you wouldn't risk the CPU as much.

No problems for uploading the video for you, it's worth it if it saves your CPU.

Can't remember who it was off hand, but someone tried it without much success.

There is a video showing ihs removal at dfi street. If you are thinking of doing this then watch the video as an idea but he puts the blade way too far in for safety. The most i let any part of the blade go in is 5mm rather than 5ft like that guy on the video did. I already know of one person who copied that video and ended up cutting 2 of those little chips off in the process

That's the one posted above, and having just watched it, yeah he is a bit over zealous with sticking the blade in.

Two issues, many sockets are higher at the back where the lever is so it will come into contact with block if it is bigger than the chip.

The second is that for blocks that use a standard clip on mount they no longer contact the core with adequate pressure, meaning you will actually get higher temperatures.

You can bend it and 40C isn't a high temperature to be honest.

Yeah what are you using to test load temps? PWMIC temps should also sky rocket as well.
