Are you looking for industrial quality graphite sheets?
Hello everyone, do you have any background in using industrial-grade graphite sheets on personal computers? I purchased one from Mouser and am eager to see how it performs. I'm curious if others have tried this before—especially since they claim high conductivity. If it's effective, wouldn't more people be using them now? I also read they're popular with Panasonic products. Would anyone like to share a video or thoughts on this?
It's a simple graphite plate, I know about the IC diamond sheet but it has a rating of 35W/m-K. The Panasonic version you mentioned is 700W/m-K.
I'm not sure if the industrial versions match the IC Graphite sheets that have been popular among hobbyists for a while. For example, the Amazon link you mentioned shows a similar product. In short, they function but don't match the performance of high-quality thermal pastes. I've seen Linus use one in recent videos, likely because it's faster to apply than paste during cooling tests. Even then, results might be better with a superior paste. I tried one myself, hoping it could help spread heat more evenly and improve efficiency. Unfortunately, it didn't work out. I don't think it's necessary to choose a different product unless you heavily modify your CPU or cooler. A good paste is stable, lasts years, and is affordable. Unless you spend a lot time tweaking components, once applied it stays put. A long tube works well unless you use it excessively. If you decide to try it, don't worry about its conductivity—just ensure it's not too big and stays in place.
We need to ensure they undergo identical testing and evaluation. I remember the IC diamond sheet performing better in one direction than the other because of graphite's properties. The Panasonic products appear quite affordable. If you choose to test them, I’d love to see your findings.
I understand, thanks! The order should arrive soon, though it might take a while since I'm in Canada. I'll place it on my PFsense box and test it out for a while before deciding on the main system. I'm a bit doubtful about the 700w/m² rating and will wait to see how it performs.
I checked the datasheet for the Panasonic components. The 700 value refers to the a-b plane shown in the graphite sheet, while the c direction runs through the sheet and is more relevant for the IC graphite specification. It seems the datasheet doesn’t list a value for that direction. The strong in-plane spreading was what I was aiming for, but it didn’t turn up.
The concern is that both options might essentially be similar products. “Sheet” can mean different things—like soft fabric or a rigid material such as plywood. When it comes to the cloth type, it offers good heat transfer when in contact but lacks the deep bonding of paste, making the overall performance less impressive. The thermal ratings might actually describe the same item. It’s faster, cleaner, and more organized compared to paste, which is why many reviewers used them before they’ve largely faded away.
