View Full Version : Best method for securing heatsink to vertically oriented CPUs?

November 24th, 2017, 09:59 PM
Hello, all.

My IBM 5160 has an upgrade ISA card in it, containing both 286 and 80287 processors. The 80287 gets especially hot. And I have another ISA card that contains a chip that gets pretty toasty. It concerns me a little. I'd like to know what's the best way to secure a heatsink to chips like this that are vertically oriented?

Thanks in advance.

If you leave it to cure while flat it will hold in the vertical position with no issue.

What David said, I've done that before on modern machines (voltage regulators etc) and it held up fine.

Well, great: I already have some of that. Exact "brand" shown in the photo. I'll give it a go, thanks.

i really like the tape version. Very hard to pull apart. Dont know if the tape i have is exactly this version - but mine is 3M and work fine!

I originally bought it to mount a heat sink but also used it to repair a rubber oven door seal. The metal hook in the end of the seal had broken loose, so I glued it back in place with the heatsink plaster. After 24 hours I stretched the rubber down and hooked it in place. That was a year ago and the bond is still strong even with the constant tension of the taught seal.
