Do heatpipes make noise?

[Cheesetogo]

At first I thought it was coming from a fan scraping up against a wire or somthing, but I've tried stopping all the fans (just for a second) to see if the noise was coming from one of them, but I still hear it. It appears to be coming from the area around the cpu. I'm using the stock opteron dual core hsf (the one with four heatpipes). Motherboard is DFI NF4 SLI-D. Could this noise be coming from the heatpipes?

They should not make any noise you can hear. Perhaps some devices on the motherboard?

Heatpipes won't make noise, unless it's the sound of your car radiator contracting as it cools when you shut the engine off!

Heatpipes, like any other pipe though make an excellent sound conductor. To this day, they build Navy ships with talking tubes in case electricity goes out.

Could a sound be coming from a component other than a fan?

 

[Luckyboy1]

Could be, but I'd suspect a fan first. You are going to have to just listen carefully in a quiet time and figure it out.

Does it make the sound all the time? If it does, you might get away, but ask others to confirm if this is a good idea for that setup... you might get away with unplugging the fan in question and booting up for 15 seconds to test.

If you really want to isolate the noise, remove the HSF and apply a hot soldering iron to the base (after you clean it). A hairdryer is too noisy and a lighter will leave crap behind on the base.

coil whine maybe

Don't read. Study this http://www.cheresources.com/htpipes.shtml

You must be young w/very good hearing to pick-up on fluid boiling inside a copper heat
pipe. It could be fin ring but if you stopped the fan, that should not remain.
IIRC, females have even keener hearing or so it seems 😉

I love the sound of air cooled M/C engines cooling down after a hard up hill run. The two
minuet snap and tinkeling of the large aluminum fins is relaxing.
