ARCTIC MX-4 (incl. Spatula, 8 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application

Working good. You get a lot and it’s keeping my cpu cool.

Excellent paste, easy to apply on laptop cpu and GPU, major boost to performance on 5 year old lenovo Legion laptop. Fans run way less and faster performance. Highly recommend.

Who knows how any of this stuff works, right? You put it under your CPU because they tell you to. You know it's working because they tell you it is. You believe it is a good price because they say so. I didn't research any tests of this type of compound, and just bought this product as a name-brand best-in-class advertised product extravaganza. Does my computer overheat? No. Does this product have any effect on my processor temperatures? Who knows? Is it worth the $$ for the peace of mind knowing I have done all I can do for CPU heat transfer? I don't sleep any better at night. Does Dell use this product? Probably not, but who knows?

I recently made some changes to my PC cases in my house and while I was moving the motherboard to different cases, I thought I should re-apply thermal paste on all the processors.This paste works very well. My Unraid Server with an i3-12100 processor is working really well and staying under 30 degrees c. The attached pic is from my unraid server.I also re-applied paste to my other PC with AMD 3700x processor and that one showed 10 degree lower temps compared to before with the same fan.

I've used the MX4 for years and have been happy with it. It's cheap, easy to apply, and works well medium powered cpus/gpus. It was always my go to. I just like it.With today's hotter and more power hungry parts, it has fallen out of grace. It's just not as good. It works in most situations, but for money, there are better options.For my high end parts I use Kryonaut. That's for an RTX 3090 waterblock, 6900XT waterblock, 5900X, 3900XT.I started to notice that it wasn't quite as good when using it on an RTX 3090, the Temps were not too much better than the stock paste, and the clocks were not staying consistently as high as I hoped.Going through the pain of tearing down the 3090 and repasting it led to the same results. Switching to Kryonaut saw significant performance increases and temp decreases.Building in ITX cases with low profile coolers with an AMD 3900XT saw the MX4 fall in line with a lot of the other pastes. Just average.I also got some Thermalright TF8 for cheap on Black Friday. It outperformed the other pastes like the MX4, MX5, Noctua, BeQuiet, Coolermaster, and some other stock pastes by a noticeable degree.I'm in the process of building in 8 ITX cases with air cooling, and a 3900XT & A520I which doesn't let me change voltage/ core clock speeds. With small coolers, tight spaces, and high wattage, you get to see what works, and what doesn't.I've been going through a lot of paste with all these builds, and testing out all the pastes I have.MX4 performed on the average side. When the good paste TF8 kept the cpu from throttling, the MX4 and other pastes failed. They all crept over 90 C and the clocks dropped.I still bought MX4 again as I like arctic fans and AIOs, but the paste has aged compared to the newer stuff that is made to handle the hungrier cpus and gpus.It is better than the runny messy MX5. It cooled slightly better, but sure was a runny mess. I understand why Arctic discontinued it.Better Options:Thermal Grizzly KryonautThermalright TF8I'll still use MX4 for repasting old GPUs and anything that doesn't really get too hot, but there are better options now.Pros:It's MX4. You know what it is, how it performs, and you like it.It's like a Honda.Easy application and clean up.CheapCons:Average performance.Better options for more money.

It was my first time assembling a PC and this thermal paste is really great.Easy to apply and the spatula helps a lotMy processor stays under 45ºC for regular tasks and under 70ºC for gaming. With stock paste it was 55ºc and 85ºcReally happy with this purchase.A remarkable aspect of this paste is that is good for novice builder like me because is not hard like other pastes, so you don't need to heat the tube.

Great product.

I bought them because i've been using the HY510 and the temperature under high stress situations were about 80/85 degrees. Today i switch from it to the mx4 and it maintains the cpu temperature 75> under the same situations, i highly recommend it. (those temperatures are on Ryzen 5 1600 underclocked till 3.6Ghz)
