I have had this tube of MX4 since 2013, it’s served me well, countless rebuilds of my computers, CPUs and GPUs alike, home servers, gaming computers, laptops, games consoles, pi4, I used this on everything. You served me well.
8th June 2013 to 4th November 2023.
The post shows more devotion than many relationships found in my family tree.
I’ve got half a dozen tubes floating around somewhere in various totes and drawers.
Not gonna slut-shame you
This would be funny if it wasn’t so true : /
Doesn’t thermal compound experies? I thought after some years it would not work anymore.
It’s important to give it a taste test every few years.
I didn’t notice any breakdown of the paste. It typically dries out over time once applied, this was still the same consistency throughout its life (in the tube)
This has been my experience with MX-4 as well. It’s really really really stable. I’ve never had to re-apply MX-4 due to it drying out, either. (It’s supposed to last at least 8 years in use.)
The same tube has been sitting in my drawer and every time I’ve needed it, every few years, it’s been good.
I have decade old tubes. Maybe some bits around the entrance can dry out if you didn’t clean them after use but it doesn’t seem to be an issue for mine as far as the inside stuff goes (of course I put the cap back on as well).
No, but you do want to occasionally rotate them around. They will separate over long periods of time.
If you have some expensive stuff that has been untouched for like a year, plunge it all out on a cleaned piece of glass, very, very, thoroughly stir it back up, and scoop/smash it back into the back side of the tube and then let it sit upright somewhere for about a month so all the air works itself back out to one end before using it again.
This really depends on how the particular paste is made. I’ve never seen MX-4 (carbon) or NT-H2 (ceramic) de-emulsify.
It’s not something you’d visually notice all that well. Just that the carbon particles (using mx-4 as an example here) will drift downwards instead of being equally dispersed in the paste. That can leave your solution you apply having too little carbon to do its job as well as it should.
No pastes are just liquid. They’re all super finely ground solids suspended in a liquid, and the solids never weigh the exact same amount as a liquid, so given time, the always start to separate.
It loses conductivity mostly due to drying out, so a sealed tube should keep it good for a long time.
I think it doesn’t hurt to try before buying a new tube. If once you apply it you see a drop in temps and fan noise, then it’s obviously still good.
As someone who upgrades / rebuilds rarely I have more thermal paste than I know what to do with. lol
I’m pretty sure I still have a bit of Arctic Silver 3 lying around somewhere…
I have a big tube that I don’t think I can ever use up. I have used like less than 10% in a decade.
That’s incredible. I typically only get 1 use out of mine.
Far out, how much you putting on? As far as I’m aware, doing a cross over the processor is all that’s needed
1 tube per processor but sometimes I get hungry and need 2.
Hey I respect it man.
Even that’s a bit much. For normal sized CPUs, a dot in the middle a tad smaller than a pea is enough to cover the IHS.
What are you installing, a threadripper every time?
You don’t need much at all, just barely enough to cover the IHS in the thinnest possible layer.
