Testing methodology
Testing thermal paste means we have to keep everything constant, including the CPU cooler, as we want to find what difference the thermal paste itself makes.
As such, we used the follow system for testing today:
- Intel i7-4790K CPU
- Cooler Master Hyper 212 LED CPU Cooler
- 16GB Corsair Vengeance 2400MHz DDR3
- Gigabyte Z97X-SOC Force Motherboard
- Corsair RM750x PSU
- OCZ Trion 150 SSD
To test each thermal product, we first cleaned off the old thermal paste using an ArtiClean kit (HERE). We then applied the thermal paste using the ‘pea' method – meaning we applied a small blob, the size of a pea, in the centre of the CPU. We repeated this process for each different brand of paste.
To stress the CPU and create excess heat, we overclocked it to 4.5GHz using 1.3v. This may not be the most efficient overclock but it generates plenty of heat which will help us see which thermal paste is best at conducting that heat.
To get an idle temperature reading, we left Windows on the desktop for 10 minutes. To get a load temperature reading, we ran Prime 95 (version 26.6) for 10 minutes before taking a temperature reading. We repeated this process 5 times per paste, taking the average of those figures to present here.

I’ve made $104k in 2016 by doing an on-line job and I did it by working in my own time for 3 or sometimes more hrs on daily basis. I followed a business model I came across from company that i found online and I am so thrilled that I was able to earn so much money. It’s very beginner friendly and I’m just so blessed that i discovered this. Check out what I do…FACEBOOK.COM/Jobs-from-home-for-US-UK-Cananda-Australia-and-New-Zealand-251232438633700/app/208195102528120/
Google is paying 97$ per hour! Work for few hours and have longer with friends & family! !mj241d:
On tuesday I got a great new Land Rover Range Rover from having earned $8752 this last four weeks.. Its the most-financialy rewarding I’ve had.. It sounds unbelievable but you wont forgive yourself if you don’t check it

Thermal Grizzly and Gelid GC-Extreme . (period)
You forgot the Mayo!

I think you needed to consider amount and cost, that Grizzly is £4.99 for 1g when EK Ectotherm is 5g for £4.49 which makes it one of if not the best performing for the money
Yep. Kryonaut.
I got paid $104k in 2016 by working online from home and I did it by working in my own time for several hrs /day. I’m using an earning model I came across from this website i found online and I am thrilled that i was able to make so much money. It’s very beginner friendly and I am just so grateful that i discovered it. Here is what i do… TIMELY84.COM
The Extreme Fusion X1 is better than the GC-Extreme on the real-time average of the HWiNFO64. The GC-Extreme is only marginally better taking the max values. Tests taking the max average incur in a lot of oscillation / imprecision. Not to mention that during most of the test the CPU is running way below the max values. Considering the price of both, the Fusion X1 is a bargain. The GC-Extreme is only better in the consistency. It is easier to apply. But it is not worth the price whatsoever.
“We repeated this process 5 times per paste, taking the average of those figures to present here.”
Are you re-mounting the cooler 5 times per paste or just running the test 5x/paste? Seems to me that since mounting and paste application is so critical, the results above could just be due to variations in application/mounting pressure if they aren’t remounted between tests.
Who honestly needs 5 grams of TIM?…Not the average consumer, that’s for sure. Not even the average PC builder.
Liquid Ultra between die and IHS, and some AS5 that I’ve had for 4 years or so between IHS and block.
I certainly have used half of it on numerous builds for me and for family and friends. Is it hard to understand that if the average consumer has the need then they won’t have to buy it again? For years even? For less money? Whilst sacrificing negligible temperature differences? Seems like a better deal.
The average consumer doesn’t build PC’s for their family and friends. I have a 1G tube of AS5 that I bought 4 or 5 years ago…it’s kind of watery now, not the same consistency as when new. The stuff doesn’t last forever.
But I’m also the guy with a syringe of Liquid Ultra that cost me 15 bucks for .3CC. I don’t care about price if the performance is there.
So what’s your point? I’ve had my Ectotherm for a few years also. Why would the “average consumer” even need thermal paste?
It’s pretty clear that it is the best value for money in this test. You’re mad for spending 15 dollars, the “average consumer” doesn’t really care if it performs as long as it works.
Mad? No. I have a 7600K at 5GHz that runs at 50 degrees under full load. Your junk TIM isn’t going to get me that. My 6700K rig runs around the same temp at 4.8. This stuff exists for a reason, not to put on your Ryzen 3 or whatever.
The average person who would need to buy TIM doesn’t need a 5G tube. Just because you can buy a large amount of something that doesn’t mean you should…That same person will probably use that 1G tube just as many times as the 5G tube before it gets thrown out or replaced with something newer.
Hahahaha whatever man, spend that money!
i trust tomshardware testing way more then this and they even state its not that big of a deal between the pastes yet here a few degrees it’s like it’s a massive things
I like Arctic MX-4 because its nearly as good as Kryonaut TG and when you build or reassemble computers as much as I do it is a lot more cost effective. ($1.75/g as opposed to $12/g)
But yeah there is less than a 3 degree difference between most thermal pastes. and less than 2 degree difference between MX-4 and TG. What matters more is proper application.
My only issue with MX-4 is that it seems to perform slightly worse when temps are higher than something like Noctua and Grizzly Kryonaut. This difference is negligible, but still something that seems to be overlooked. Also, I haven’t had the best of luck with it on water coolers either for some reason. It’s still my preferred paste. Never have I taken any build apart and found any parts of the paste looking dried out at all.
Would be nice if Best Buy actually sold these brands rather than their terrible Insignia brand or the useless Thermaltake TG-7. They used to sell Antec Nano Diamond Formula 7 which was the best in their store, but this stopped a few years ago unexpectedly. For those who have never tried TG-7, it’s pretty bad and dries up extremely fast. As for their Insignia brand, well “paste” isn’t the term for it at all as the thing looks like it’s a melted blob in a tube and also dries up rather quickly.
