"recommend me" a glue

[thomsbrain]

OK guys, I've got a couple fans that are placed over my HT receiver, which gets pretty hot. They are coupling with the grill and causing a small amount of buzzing vibration that I'd like get rid of by gluing a bit of rubber to each corner. I just need something to get the plastic slightly off the metal grill. But since this will get pretty hot, I need something that won't just melt and make a mess. I figure I'll use some small speaker wire-insulation trimmings to do the actual de-coupling.

Will "super glue" hold up to heat? I thought about using rubber cement by itself, but was told that it will melt.

epoxy?

Wiki says it's tough. Can I find epoxy at a hardware store?

Hardware store, Kmart - yup.

If you need to glue plastic to plastic, look for Devcon Plastic Welder epoxy. It's great for ABS plastic, which a lot of electronic appliance cases are made from. Be warned: It stinks horribly until it cures. Use it outside.
It will not work with polyethylene (#1, 2, 4) or polypropylene (#5).


And with 2-part epoxy, do NOT mix it on the surface(s) which will be adhered.

JB Weld. Good up to 500 degrees F (claimed)

high heat epoxy..sometimes its a putty.
found at hardware stores.

that being said... a home theater system doesnt qualify as high heat.
that stuff handles hundreds of degrees.

a regular high strength plastic epoxy will do well for you.

Epoxy is good, but kind of a PITA... messy.... This isn't mission critical, cyanoacrylate will be fine.

if you have fans on it, it wont get as hot as you'd think...

I agree...although you and my old boss are probably the only people I've encountered who habitually use the actual generic name for the stuff.

Silicone sealer? The tube I have here says that it's "not for use on surfaces that will exceed 400F" so I think you'd probably be safe.

Instead of gluing rubber, why not just cut out the middle man and use high-temp RTV? It'll withstand the temperature, hold the fan in place, AND its rubbery.

This, for example:

How hot do you think it will get? I've had luck gluing a 80mm fan DIRECTLY on a CPU heat sink with hot glue - it never melted. This was sorta an experiment as I had a feeling it would not work, but it did, to my surprise. The key though is the fan has to be running, if it stops for whatever reason then the glue may melt. This is an easy way as everyone most likely owns a glue gun and they're easy to find.

The silicone stuff and other suggestions sound better though.
