Is it possible to lap a HDT-1283 heatsink?

[CarolinaKSU]

So I took my heatsink off today to turn it around with the fan blowing towards the big top fan in my case and while putting the thermal paste on I got to wondering if it would be possible to lap an HDT type heatsink like my Xigmatek 1283. I was thinking it would probably wouldnt work because the base isn't just a solid piece of copper like most other heatsinks. Plus the aluminum that is in between each pipe on the block dont seem to line up exactly either and would make it a huge pain to sand down to a completely flat surface since the two different metals will wear down differently.

don't try it. You wouldn't want to sand through the heatpipe.

well you could do it but you would have to be vary careful about doing it i would check the bottem almost every rub back and forth but it can be done

if you check out doghucat's post in this tread he lapped his Xig HS and looks fine

and this is the possablities if you lap it too much

Don't do it. Just go and lap your Processor. The bottom of the s1283 is already rather flat to begin with.

I have lapped a HDT HSF. You have to be very careful and go slowly. Use a fine (1000+) grit.

It doesnt take much to get a flat finish. And remember your are not trying to get the pipes flat with the base.

I don't have any of the HDT heatsinks since all of my CPUs and GPUs are only the bare die (I took the lid off my Opteron) but you can be certain that once I do buy one I'm lapping it. If you want to go extreme overboard you can fill in any gaps between the pipes and the rest of the base with solder then lap everything down. Like everyone has already said, be careful.... but if it were me I wouldn't even think twice.

Personally I would not lap a s1283. Maybe something like the TRUE but not something with DHT. You could go and screw yourself out of a good heat sink e_e. If you do lap it, make sure that you have a stock Intel heat sink ready so that you have spare just in case.

have you had any experince in lapping? if you don't, don't try it on the 1283

I never have done it actually, although I would like to try on like a AC64 or the stock intel one or something. But now, no freaking way on a 1283 apparently.. I just wanted to know if it was even possible since I couldn't remember seeing anyone ever doing it.

People do it all the time but I wouldn't bother. I haven't read of anyone screwing theirs up but I have read of quite a few people lapping them. I own one and I've lapped many heatsinks in my time and I would still not lap this one.

I haer that lapping a direct touch base or whatever it's called can acctually hurt temps. It's not worth it, imo.

Just lap your proc, it will deem the same temperature benefits, just less risky.

Mine went down about 3c.
