K5 PRO 20g & K4 PRO 10g Thermal Paste and Putty Pad Replacement Set Compatible with Apple iMac, Asus ROG, Acer Nitro, MSI laptops, RTX 3080, 2080TI, 3090, PS4, Nintendo Switch, Xbox, CSGR

I watched a repair video on Youtube regarding the 2009-2011 27 inch iMac Graphics Card Oven Bake and followed everything exactly, including the cleaning of the grease and pads on the GPU. Then I baked my two cards (one was from iFixit.com which started to fail) and the other is the original. I covered the refurbished iFixit GPU and other parts of the board with the thermal paste and pad set from Laboratory Produced by Computer Systems Laboratories , and I couldn't be more blunt than "it worked." It's only been 6 days since re-installation, but I can say that the computer is working properly. The next step is replacing the HD with an SSD. Fantastic.

Very good. used in PS3 - no problems

These are not thermal paste for ps4

The K4 Pro thermal paste didn't make a difference for me over the stock paste on my laptop's A8 4500M. I also tried it on another laptop that had an A10 5750M and couldn't really see a difference. The K5 Pro putty that it included doesn't work well enough to justify taking your machine apart just to apply it. It's worth considering for someone who is in the process of building a PC or upgrading a laptop, but if you already have a machine that is overheating you shouldn't expect neither the K4 paste nor the K5 putty to make a difference. If you have an AMD APU that is shutting down constantly like I do, then you should know that this product likely won't solve your problem. I went ahead and gave this product three stars because it does do what it is supposed to do. People just have unrealistic expectations about what these solutions can do. My only real complaint is that it took well over a month to ship.

Worked fine on the apple TV but used in place of thermal pads in Xbox one with nt-h2 paste and the system gets so hot the fan is loud as my ps4 when playing cod

I ordered this product to repair the video card in my brother in laws' Apple 27" iMac that was having overheating issues and had stopped working. It worked great! A little gooey, but the included stick helped me get the product onto the chips. The iMac runs perfectly again and the temps are fine! Would definitely purchase again.

Fixed the YLOD on my PS3. Simple fix and fast shipping. I am very pleased with this purchase!

So the k5 as stated is good for the memory chips etc, the k4 says its suitable for gpu/cpu processing chips, but it's not. Unless your ok with 10-20°C higher than legit thermal paste for those applications. This product should actually have 2 ratings as they're 2 different products. 5 star for k5 as it's intended use and 0 star for k4 as it's intended use.
