K5 PRO 20g & K4 PRO 7g Thermal paste and Thermal Putty Pad replacement Set Compatible with Apple iMac, Asus ROG, Acer Nitro, MSI laptops, RTX 3080, 2080TI, 3090, PS4, Nintendo Switch, XBOX

Worked well.

Used on 3 Acer Nitros, and it worked great.

It's been nearly a month since I used the paste, and the computer is still functioning. My issue was that the graphics card conked out, and I discovered the odd notion of baking the graphics card...long story short, bake went well, attachment went well, computer is working, and temperature is low! The computer is working 26 days past its initial ETD, so I'm a happy customer!

I used this kit for my iMac 27 GPU 3 months ago, everything seems great so far.Good product!

Do not use the K4 pro my cpu immediately hit 100C when I ran a benchmark . The k5 pro is awesome though and works great.

Never used the K4 before so first time and was a easy product to apply and does it's job. Used K5 also which is a great alternative to pads

The K5 Pro was essential for repasting an iMac, but you may as well just throw the K4 tube away.I trialed the K4 against Antec Nano Diamond and GeLid Extreme in a MacBook Pro.The K4 resulted in near immediate thermal throttling down to 2.4 GHz and over 104C under load. GeLid let the same CPU run at 3.44 GHz and 101C. Antec Nano Diamond achieved 3.4 GHz and 102C. K4 Pro wasn't even a distant contender against the other two TIM's.The included K4 tube immediately went into the trash after my test results.Buy this for the K5 Pro, but don't expect the included K4 Pro to be actually useful.

My old AMD Radeon card failed in my iMac, so I removed, cleaned, and baked it. I used this kit to replace the thermal paste. The card is working again. I'm not saying it was just the thermal paste, and nobody really knows why the bake works, but the heat sensor reads fairly low considering how hot this device can get, so the thermal paste is working well.
