Transfer heat but not vibration for hard drives?
have we found anything yet that can transfer the heat of the hard drive to the hard drive cage without transfering the vibration/noise? have been away for a while

These Nexus things are the only devices that I have had any success with:

They where able to reduce the HDD temperature a few degrees, but are nothing brilliant.

Depends on how hot the HDD gets and how tolerant it is to higher temps? But for a newer efficient drive (think WD Green), you won't ever have a problem. Of course, those drives are ridiculously quiet to begin with.
In the end, it's simpler to suspend the drives and place a slow, inaudible fan in front to move enough air to keep them cool and forget about vibration. But if idle whine is your issue, the simplest choice is to buy a new HDD, otherwise your stuck with encapsulation.

Unless you go with a Velociraptor, you're not likely to find anything that performs significantly better as is quiet as well. All the newer WD and Samsung drives are very good and should be quiet enough for anyone.
Suspend those drives, maybe use a fan on them if you need to, and they should be quiet and cool enough for anyone.

Liquids can conduct heat very well but won't conduct vibrations much at all. Anyone want to try dunking a hard disk in a vat of distilled water sometime? Come on, it's all low voltage and moving parts are sealed in.
It's already been done with a complete system with oil so a hard disk on it's own might work.

The Whimsical Wizard of the Drive Platter Hollows!SlaveToSilence wrote:thats where the wizard lives
So anyway, I googled it (was curious myself). And I ran into several theories, ranging from plain open breathing holes to special pressure valves. Eitherway all of the theories seem pretty clear about covering up the holes being a generally bad idea.
Here's a couple links on the topic:

Anyway, if you like building stuff, I suppose you could pretty easily run rubber tubing from outside the liquid enclosure to said holes.
Mental note: Next time I have a broken drive, see if it collects a whole lot of water if you submerge it. If the holes are pressure valves, it probably won't. If they are breathing holes however...

Yes, usually the HDDs in a submerged system are encased separately or outside the liquid entirely. I believe that those holes are pressure valves that balance the pressure generated inside by the spinning platters.
Submerging a HDD in anything is a bad idea.
As for liquids conducting heat very well and not vibrations, I can only ask if you've ever gone underwater in a lake with a motorboat somewhere nearby. The denser the medium the easier vibrations are transmitted. Which is why the vacuum of space is silent.
There is no magic bullet here, only soft-mounting....

The gel pack works in two ways:SlaveToSilence wrote:do gelpacks work for 24/7 systems or just ones that are only on in the day? (slow to warm up but need to cool each night or become ineffective)
It kills sound by absorbtion and the viscous gel is heavy, so adds mass, so damping higher frequencies considerably.
It conducts heat to the enclosure far better than an air gap, so as long as the enclosure can dissipate the heat generated by the HDD, the drive will stay cool (the enclosure will often have a greater surface area than the bare HDD, so drive temperature can be less than the drive in free air).
I've run a gel pack cooled HDD for years in my silentPC* (actually I had one up and running before AlleyCat posted his idea on this forum ) I've run it 24/7 for weeks on end. I had a minor problem with an early home-brew gel pack, but since using a medical pack I've had no problems at all.
