Guys, don't bother with Thermal Pads, save yourself the pain! :)
Seriously, I have spent the last 9+ months trying to locate the exact thermal pads for my Alienware 17 R3 without any success! Unfortunately, the factory thermal pads are very soft (probably 15-20 Shore 00) and are 0.8mm thick (Measured numerous times with my digital calipers!). Don't bother emailing Alienware or Dell, they simply will not rely. That being said, there are no commercially available pads that will work properly. If you don't believe me, then please crack open you laptop and you'll see for yourself that the heat sink does not sit on the CPU and GPU properly due to the negative push back of the thermal pad! Ok, well along came K5-Pro from our friends in Greece, Thank you! Their application method is a bit Betty Crocker for my liking, so I decided to use an old Arctic Silver 5 syringe applicator that actually put the right amount exactly where I wanted them to go, the results... a factory look that works! Finally I can assemble my laptop and get back my gaming! Thanks Computer-Systems! ευχαριστώ!!!

    can be used as thermal paste (found out because i ran out of thermal paste in the middle of re apply, and this i used as a last resort for thermal paste and it surprisingly works decently not as good as thermal paste but gets the job done which more than what can be said about any thermal pad that i know of and relatively stable (using it on a laptop ) as for the VRMs the temps are VERY noticable from before id say about a 8C difference on the temps of there from what i can tell from monitoring , will update if any changes arise WOULD RECOMMEND, also make sure you get thermal paste along with it or have enough when you do swap out thermal pads with this stuff its quite effective and reasonably thick

    This thermal paste is perfect for replacement of OEM thermal paste on components when upgrading or replacing thermal paste.

    I used this specifically for some iMac GPUs that I reflowed to repair rather than replace. I have reflowed a few GPUs this way, and the first time around I had used thermal paste on some of the modules that had originally had thermal pads. I found that the first time I did this the GPU began to have issues about a month after.

    I did some research and came across this much thicker thermal paste. This allows for a thicker application to be applied to the modules that previously had thermal pads and ensured a good contact was maintained with the heat plate.

    The 20g container will last a very long time and it’s nice that a small spreader was included. The spreader looks like a small painted popsicle stick cut to an angle. Although it is useable, I found it a bit short, and used a long thin spudger I had on hand. This isn’t an issue to me at all as the job can still be done with the supplied spreader.

    Overall I’m very happy with this purchase and highly recommend it for anyone replacing thermal pads. Especially for anyone wanting to try reflowing an Apple GPU rather than buying a replacement. This helped save me hundreds of dollars.

    Ordered this to clean up and re-thermal some older rigs and graphics cards. Works well in terms of thermals, but it is a pain in the butt to apply unless you have a spare spreader laying around. It ships with a 1 inch popsicle stick as an applicator. Immediately tossed that and used an old Arctic Silver spreader. If you're looking for thermal compound on a budget, this stuff works well.

    You have to use a fair amount, I put it on the VRM only on my GPU as the stock thermal pads were constantly hitting 100-104c and thats just unacceptable honestly.

    Using this brought temps down to a far more respectable 85-90c when under full load, around a 15c average drop. Very impressed.

    Huge pain in the ass to apply properly though, very messy but it works.

    If you already have a very high end video card that isn't overheating with its stock pads, I probably wouldn't bother using this though, best used on laptops, macs and under-performing thermal pads on things. Wont outperform a high quality thermal pad, but it absolutely will outperform when you find a pad is not performing properly on an existing piece of hardware.

    DO NOT USE ON A CPU OR GPU CORE.

    Not suitable for very hot VRAM like on the 3080. I bought a 2nd tub of this thinking my coverage was inadequate with the results I was seeing but no, the performance is awful compared to aftermarket thermal pads. My temps are 20c hotter, hitting the thermal throttle limit while performance is down 20% and this is without the overclock I had previous.

    I'll have to scrub off most of this messy goop and go back to thermal pads.
    I'm sure it's fine and convenient for lower end components and it's probably worse than stock for my RTX 3080.

    While my iMac model has heat issues, this paste was relatively easy to apply as a replacement. Temperatures are no different than before (but keep in mind heat issues) so the paste is pretty good.
