After reading through this thread I decided to try out some MX5. I had been running various pastes over the decades, AS5 to Kryo to LM. Was planning on doing a mass repaste on a bunch of hardware we purchased last year. I wanted something that was easy, and would last. MX5's claimed 8 yr running time, temps, and price (2g for $5.xx at amazon) seemed like a no brainer. Grizzly was like 4x's the price.
First thing was my laptop. I thought it may have been a bit watery when I applied it, but using an old grizzly spatula, it seemed to have substance, and covered the chips nicely. I then "painted the cooler jic. I was expecting at least a 5 degree drop, which is fair since the laptop has been in heavy use, the old paste was mostly dried up, and was just cleaned.
Long story shot.., Temps went up slightly, or were the same. No one said anything about a cure time but after an hour of various tests, it was clear. So I took it apart again, and added more MX5. Ran it overnight, and now I think I'm getting 1 to maybe 2 degrees better than the stock stuff, but I'm not sure if that was any better than than when I originally bought the laptop. I'm in the 80's after running 3dmarks time spy which is basically the same as when I originally got it. So it's not even a mounting thing. Temps would be much higer if the cooler wasn't flush.
I ordered 2 tubes when I saw Arctic had 2g tubes for $5.xx. Arctic had 2 different listings for the exact same (no spatula) 2g tubes, but one Arctic listing had it for $1 more. Now I'm wondering if it's QC thing, or they were actively selling some inferior paste for a buck less. I won't be ordering the $1 more MX5 2g tubes either way. I'd rather bite bullet, and pay quadruple for stuff that works. I'm starting to see how some people are saying that this stuff isn't all that. Reviewers get prime samples straight from the company. No chance of inferior paste going there. I got mines from Arctics store on Amazon.
I might do more testing. Might open the 2nd tube. Might make a return. Not at all impressed.
