    is it influenced by the volume that you are listening at? cause ive noticed some kind of tremble-like sound when setting high volume on my current laptop and on others aswell,so meh,if it aint noticeable on lower vol,then its harmless.

    Just did my worst pastejob ever. First time using Gelid, it was a mess. Too much and tried to remove half, what a blob lol. Next time Ill heat it first. Temps in XTU the same as with stock paste (proper pastejob by mysn btw). I will do some tests then check the spread and repaste.

    What surprised me was the fit of the heatsink. It was less of a hassle then with my HM. On that I have to wedge it abit around the fan. With this I just drop it straight down in a perfect fit.

    It isn't perfect unless it sits perfectly on it to spread the paste. But yes, it is easy. To get the best seating possible, it will take practise.

    As close of contact as I've had so far...

    Try, try again. Also, check the contact as my photos show. My spread was horrible before lapping because the cpu was badly concave! But worse temps than stock, that is a mounting issue. Once you set it down perfectly, do not wiggle it. Apply continuous downward pressure or air can get in.

    Before I did my lapping I took very careful measurements of everything and it seems as though the heatsink is convex to fit the concavity of the CPU not much but ever so slightly. This is either by design or mine just happened to be that way. Either way after polishing and lapping they are both perfectly flat and temps did drop significantly so if they did do it by design they failed...

    Btw, new heat sink and a finger sander was ordered last night. So I'll check fit first, then lap the heatsink (all parts used with any thermal interface material including pads) (and clean up the cpu), apply the thermal pads(fujipoly 17w/mk), and check where it's at. If the one corner is still high, then the mb gets pulled, mounting arm leveled, and pictures will follow. Also, @superkyle1721, how does your contact compare to my posted pics today?

    I would say mine does appear to be more uniform. I have plenty of paste so what I'll do is in a couple hours I'll pull my heat sink and take pictures. It's really extremely even now that it has been lapped and polished. Plus I just trusted my first paste job so I'm curious to see if it is even a good one or not. Updates to come.

    After lapping, the one corner that previously gave an issue on contact (before my RMA) reappeared. Because of that, it will have to be readjusted once more for that corner. If you have better contact, then you did an excellent lapping job considering the CLU did practically nothing for temps. That is usually seen with either poor contact or amazing contact between lapped surfaces. Perfect contact eliminates the benefits between a high quality paste and liquid metal.
