Cleaning EPOXY off core

Blueneko · Post by **Blueneko** » Tue Dec 17, 2002 1:44 pm

I remember when someone had a VP6 board with watercooling and they ripped thier whole chipset clean off, but i also read hold one of the cans of blow off, and it turns the epoxy brittle and easily removes the bond epoxy has, but how do you clean the dried up epoxy off the chipset????
Was in the advanced cooling section!

I use WD40 to take any paste off and then wipe the surface to be cooled with rubbing alcohol to get any residual WD40 off.

Make sure there’s no WD40 on the surfaces before you put on the thermal paste!

I have anti-static wipes, but there dosent seem to be enough alcohol on the wipey to actually do anything to the chipset (I removed heatsink off an older geforce 256 ddr card, since the fan didnt work anymore, and it needed a special fan, I have a nice copper chipset cooler for it from vantec

or just a large copper block

Im at work, i dont have any wd-40 laying around, and this is an office-type enviroment, there may be some wd-40, but..... well what else coudl I use?

Well, the WD40 works very well because it's a heavy duty degreaser; it literally disintegrates any paste or epoxy it comes in contact with. The reason to clean the WD40 off is not because it can directly harm the computer, but because it has virtually no thermal conductivity.

I'm not sure of any other 'household' product you could use to clean the chip other than rubbing alcohol.

Oh yea, Q-Tips come in very handy!

Ok nm, its clean Used another swaby and added a bit of pressure and the wax-on, wax-off routine, worked!

I should have thought of that

Still, if you have the chance, use the WD40 and rubbing alcohol to clear the chip of paste not visible to the naked eye. Those damned micro crevasses!

LOL, heres a question, can the wd-40 help the frozen fan that came off?
Its not ball bearing.

Not sure, would have to look at the fan myself. What's the matter with it? Just won't spin, or spins slowly?

While trying to spin it, it broke and fell apart, its ok, ill just attach another larger sink on it anyway

Thanks for help

WD40 is great, but go easy on it. It's slightly abrasive so you may end up making the surfaces of the HS and CPU less flat.

I always use surgical spirit (is that the same as rubbing alcohol? We don't use that term here in the UK).

I guess it is!

Surgical Spirit, I like it...

Yeah, the stuff that your Mum puts on your knee when you fall over when you're a kid, and it stings like hell and you cry.

How about liquid lighter fuel, the stuff you put in Zippo's

maybe a bit out of this topic, but guys?...

Has anyone of you tried lapping BX chipset?

I would like to try that in the bnear future, but would like to know if someone did it before me and how about the results...

InactiveX · Post by **InactiveX** » Mon Jan 06, 2003 8:55 am

That sounds like a lot of work and high-risk for very little benefit to me, but if you try, let us know

I don't think there's anything to sand off?

it is just I read one article about one guy lapping GF4 GPU and so I thought why not, cause the package of the BX chipset is quite similar...

Well, how deep could be the real crystal under the surface of chipset?

Did they mention it working after the procedure?

o yes it was working and it was even overclocked farther...
Well, they also overvolted the GPU and GF4 memory....

I will try to find that paga, cause I just don't remeber where was it...

that's just one I found on google, but the other I read used a bit different technique for lapping and it did not include desoldering components before lapping

Hi im the new guy in town .. reading all this talk about WD40 i have a question !!!!!!

Does any one even know what WD40 stands for ???
Well I do and it stands for "Water Displacement on the 40th try"
meaning it removes water from any electrical surface or any surface at that , 100% displacement
I have taken cooling fans run them under hot water and soap rinsed them well of the soap and flooded them with WD40 and shaken let sit about 5 minutes and whamo fan is like new ..
just thought ide share my WD40 expieriences seen how it was invented in my home town of san diego
it has uncounted uses like starts cars carberated of course and breaks 100 year old rust from bolts etc...etc...
"I think if you work on PC's you gotta have a can of WD40 around...
