Nice work!
Antec 620 right on the die?

Hopefully it still works. What exactly is beneath the green silicone? What could you be damaging by scratching it? Because it just looks like a copper surface..

Yeah, I'm going to put the 620 right on the die. I just had time to pop it off today when I finally worked up the balls to do it. Funnily, I knocked off two small resistors (not on the chip but on the pcb around it). They should be easy to put back on.

Also, I read that you want to make sure to use non-electric conducting thermal paste on the die.. I bought some Antec Artic Silver stuff from my local computer stuff, and I didn't see anything on the package pertaining specifically to it's electrical conductivity.. Should that stuff be ok? Or do I need to get some stuff that specifically says that it doesn't conduct electricity?

You knocked off transistors on the PCB? WOW good luck with getting it to work now. How'd that happen? When tapping the razerblade?

The reason why you want a non-thermally conductive TIM is the transistors around the die. If you use too much there's a risk it could connect transistors and fry...

Have you tried to test the card yet?

On a mod I did on a third GTX480 I had to drill out a stripped screw head. In the process I knicked a corner of one of the resistors on the back of the PCB and took of a chunk. It worked fine. I was lucky.

Yeah I figured as much about the TIM, but what I was asking is if this antec stuff should be ok or not.. How would I tell?

And as far as the transistors go, yeah, it probably happened when I tried to lap the IHS while it was still on the card. Bad move on my part. But have some faith man.. it's just a simple matter of soldering them back on. I have all the tools and the skills necessary. Plus, I have both transistors. I'm not just going to leave them off lol.

Funny story -- I accidentally knocked off a capacitor when first taking the shroud off my 470. One of them is right behind one of the tabs that you have to release with a screwdriver (or other small object), and I accidentally pushed the capacitor instead of the tab. I figured out which kind to get, ordered a replacement part online, and put a brand new one on. It worked fine.

Accident prone man...you need to play some Operation man...lol

well I guess we'll wait and see how it goes...good luck! If it works. You'll freak by the temps. My card is now settled down to 42C max @ 22C case temp....not bad...

I heard the antec stuff is actually pretty good. You won't need even close to the amount thats on the cooler so I'd scrape it off with something plastic like a 'mysteriously free fake money card' and then use a little ball or stripe of the paste for the die.

Artic Silver 5 is OK to use, but be very careful not to overuse. It is electrically conductive. The silver in it is the reason it's conductive. Ceramique is their non conductive TIM IIRC.

I use Shin Etsu G751 myself. Slightly better performance than AS5 in various comparisons, some of which I read here on OCN, and it is non electrically conductive. thumb.gif

I'm emailing Intel asking them if the i5-2500k has a soldered on IHS. If its just pasted and held on with the glue Im taking it off, if its soldered, not going to touch it.

Well...I guess we'll be finding out soon if its soldered or not....man I hope I don't kill a $220 chip....

Good luck and let us know the results with pictures and temps as soon as you have them. thumb.gif

Man...aint no way I'm trying to pry this IHS off the i5-2500k. I just cannot break this chip. If I had someone from here that's fryed their chip and its dead I'd love to test out my theory on that or have someone try and crack their IHS on a dead i5 before I try it on my working i5.

I tried to put some pressure on the IHS but it wouldn't budget. I couldn't get my razerblade under the IHS and cut the glue either...I relapped the IHS on the i5 and then put everything back together...wouldn't boot. Reset CMOS, nothing. I took it out of the socet and realized i bent a bottom pin...WOW never knew that pins were soo easy to bend. Fixed it and thank God it still works!

wheew. SO concerned when I hit the power button and it turned on then off again...uG!
