The imprint left by AS5 should be consistent across the base. All four corners and the center should have the same consistency otherwise the base or the processor is not flat...usually the base of the heatsink.

Well the AS5 manual says to do that. Well not to smash it down. The pressure of the heat sink will spread it.

I never spread it. You either end up with too much or not enough.

Ya check it out, i just reseated it again.

If i put one drop of thermal paste and let the heatsink spread the paste, i get contact.

But, if i spread the paste myself into a thin layer, then put the heatsink on then take the heatsink off to check if the bottom of the heatsink has paste on it, theres NO paste at all on the bottom of the heatsink.

I'm gonna see about contacting Zalman about an RMA.

When you take it off take a straight-edge and check the base. If you can see light between the base and the straight-edge the base is concave. Either RMA it or draw file it flat with sandpaper. RMA if you are in no hurray otherwise it takes a lot of elbow grease to get it flat and then polishing it to a mirror finish. A lot of overclockers like to polish the base.

I really dont even want to deal with RMA at this point. I think I still have some high grit sandpaper in my basement left over from when I painted my case so maybe this week I'll sand it down. What I'll probably do is just buy a Tuniq Tower or one of those Thermalright Ultra 120 extreme's. I've had really good experience with Thermalright products in the past.

Actually draw filing is the wrong term...my mistake, I use to do this first thing to aluminum heatsinks that seem to never have a flat base. The correct term is 'lapping.' You can see what I am talking about here.

Default Re: Zalman CNPS9500LED temps too damn high.

Hmm...I'm going to be installing a Zalman CNPS9500AT hopefully tonight assuming my new Lian-Li case arrives as expected...perhaps I'll try out putting a dot of AS5 in the middle of the CPU and letting the heatsink spread it. I've always spread it using a razor in the past, but I've always felt that was a huge PITA.


Sorry about your temps, steve. I hope you get it figured out (and that I don't experience something similar...)

EDIT: And I should say...I've got my CPU up to 3.0GHz and I'm idling around 50 (sometimes a bit lower, depending on the room temp) and it never gets above 60C at full load. That's just using the stock Intel heatsink, but I'm only at 1.3v.

Well the Tuniq Tower is definitely working wonders on my E6600. I have been at 3.5ghz @ 1.41V now for several days and it idles at 33-34C and is mid 40's at gaming and mid 50's on Orthos. Much better than my Zalman 7700. Ultra 120's are supposed to be great too. Good luck!

Holy sh!t!

I put the non-LED version of this on my CPU last night finally, in conjunction with my new Lian-Li G70 case, and the CPU is idling at about 40C now and only gets up to 46C under full load at 3.0GHz!

w00t!

I bet it'd be even cooler if it wasn't started to warm up outside and my apartment wasn't on the top floor with all of the heat from below rising up.

Man...this HSF ROCKS!

It only goes up 6C under load? After orthos for a few hours and in coretemp? Wow.

No, just using Prime95 after about 20 minutes (I was in a rush this morning ). I'll give it a more thorough testing this weekend.
