Removing the A64 IHS

[cadaveca]

listen, take off the IHS, slap some AS5 in there, and put the IHS back on...makes for a better mount anyway...and just make sure that you cover the complete top of the IHS...it will all turn out good that way. 2600+ sempy @ 1.775v running FAH 100% load....41c w/ thermaltake beetle....

[Der_KHAN]

ok, i took the IHS off my SD3700+ today

running prime large fft now at 2860mhz, before i was at 2700

temps dropped from 56°C load to ~40

I think it is very tempting to remove IHS for all these people reading this thread It is really not hard to do, but remember there is always risk of damaging your chip or not gaining anything ... however I still think it is worth it ... IHS makes a nice keychain

remember do not poke the razor blade too deep - 0.5 cm is enough.

[Borgschulze]

I think I am going to do this.
Be the first Sempron without an IHS?

[Ref]

Maybe

As your core is 90 nm then you have much bigger reason to remove it

Wish you luck

Still thinking about it...
Two more questions, tho:

1) What happens if you try to start the computer without a heatsink (i.e. without contact), just in case it happens? I've heard that A64's should be able to handle this and simply shut down in time, will they?

2) Is it easy to get the IHS back on? Again, see above question, what if the contact between core and IHS isn't good enough?

Should i enconter any problems when putting 7000B-ALCU on naked core ? When do i know core has good contact with cooler and how do i know if i strighten it enough ?

i had to bend the bar that holds down the heatsink for good contact. not too difficult though

exscape. technically, yes, it'll just shut down, but i wouldn't try it...

i didnt quite understood you :d

What did you gain with better contact?

You mean you bent those, or what? :o
I don't feel like getting my HS out of the computer just yet so I'll ask instead

[exscape]

Bah, didn't work out too great. Removing it went great, but I couldn't get the heatsink to sit stable at all... Even when I screwed it as hard as possible (well, almost) it wiggled back and forth *way* too much for me to even try it. I glued the IHS back on and put som AS5 in there tho.

Which Heatsink are you using ?

[exscape]

CNPS7700-AlCu. I might have done the same even if it did fit though, the core is sooo small that I got scared just thinking about the huge heatsink

[NoStra]

it isnt like it provides that much better of temps anyway

yup, before i tightened it down, the heatsink was practically wobbling around on the lid-less core.. not a good thing.

[exscape]

What part of the heatsink did you bend? I really want to try again and I had the exact same problem, I could basically run the heatsink along all the edges of the core!

That pretty much answers it.

[exscape]

Nope, 'cause I still don't see if it's the part that is actually part of the heatsink (a long, straight metal bar) or the S/L-type thingys you put the screws through.

[Ref]

the S/L-type thingys you put the screws through.

This one.

[exscape]

Still doesn't work.
The clips just bends back when I screw it to the motherboard and everything is just as loose as before.

Try to insert something between the clip and heatsink.

What The?!?! I made a new post and it's now gone? What gives?

Anyways, I bought an XP-90 heat sync and with the IHS off with artic silver 5 thermal paste I get a load temp of only 35C at room temp of about 20C with my alpha6 the best I could ever get was about 42C under load. I can now overclock 80Mhz more as my max and with default voltage I can clock 50Mhz higher. Not bad for what was an already low temp. To test how stable this was I used super PI with 8M digits.

What heatsink have you used before?
