MY HEAT SINK IS SCRATCHED UP, IS IT NORMAL????

[IbZa]

I've recieved a HSF from 2cooltek, GLOBALWIN FOP32-1, the bottom of the heat sink has little sratches on it, but not in the area of the thermal pad, is it normal or do I have to shipp it back?? Also I went on the comp. show last Sat, and every single GlobalWin that I saw had similar scratches, please let me know if I can use my HSF or not.

P.S. Will thermal pad work ok, or do I have to get arctic silver compound? (I do not plan to OC my t-bird for now)

IbZa,

If you were to put the heatsink directly on the processor (not a very good thing thermally), then the scratches are a bad thing.

Hopefully, you will be using thermal grease or a thermal pad, so the scratches are irrelevant.

Make sure that you use a *THIN* coat of thermal grease (more isn't merrier!) or the thinnest thermal pad that you can find.


Good luck...

FYI-I think this shoulda gone in 'Overclocking and CPUs'

Anyway...All heatsinks usually arrive with lil scratches on them...just sand it down with some high grit sandpaper. As for the thermal pad, throw it away and at least get some silicon thermal paste (the cheap, white stuff). Acrtic Silver would be nice, but since your not ocing...its not worth it.

EDIT: Woah...almost sametime. =)

how do I polish out these scratches, i also know that polishing increases conductivity, which sand paper do I use?

Here is a recent article that may help. http://sysopt.earthweb.com/articles/lap/index.html

Took me about 3 hours to grind my **** FOP 38 smooth, it was BAAAAD, no way was I putting it on like that, looked like it was time for them to change the rock spinning in the milling machine...

they may not be scratches on the bottom but milling marks.
thats just the way they are machined.
thats as smooth as they want to get it!!!
if you want smoother you will have to lapp it yourself.
meaning sand it with very fine sandpaper untill you have a smooth flat bottom.

If the scratches are deep, try using sandpaper first. If they're shallow, grab some metal polish and start polishing. It takes a while but sooner or later the metal polish eats away at the metal leaving a shiny surface =)

No problem http://sysopt.earthweb.com/forum/smile.gif But yeah I have a FOP38 and I'm about to take it out and polish it up a bit. My cpu is kind of warm right now due to those 'milling marks'. http://sysopt.earthweb.com/forum/smile.gif

I need to go pick up some sandpaper http://sysopt.earthweb.com/forum/wink.gif

I have just finished lapping my FOP32 and I must say I did an outstanding job http://sysopt.earthweb.com/forum/smile.gif http://sysopt.earthweb.com/forum/smile.gif http://sysopt.earthweb.com/forum/smile.gif. Now I can see my reflection in it and it is as smooth as sheet of glass. I started with 150, then moved to 220, and finished of with 1200 wet. I love it!!!! Can't wait til tomorrow when I will put that badboy on my t-bird 800 with arctic silver compound in between. I hope it won't fry my CPU it shouldn't. I have a thermistor anyway so I wiil be able to see if the temp. is rising to abnormal levels. Thnx SysOpt!!!

[IbZa]

you know you might be right, they might not be scratches, but i will polish it with fine grind paper anyway

Joel, the reason I have posted the same topic on CPU's and Overcloacking is because i though it belonged there, that was after i have posted here, sorry
