this HDD block design feasable?

Pureh20 · 03-24-2004, 12:39 AM

the pictue below is a design i made of a hdd blocK.
this design will be mounted in two spare 5.25 bays with an 80mm fan BLOWING OVER the heatsink;
so as well as cooling the hdd its also meant to cool the water

anyone see any flaws, or any optimizations?

yes, it is feasable. But y bother. read this artical here and u will c y it is far to over the top and seriously not worth the effort.

If you've got airflow over the HDD, then add the heatsink but skip the pipes...

Why?

Because that is no efficient way to cool the water and the HDD will manage with just the airflow and the heatsink. So by adding the pipes I guess you will just put more heat in your WC system...

hmm what if i do it for two drives?

I don't see the reason. Why people go WC on their HDD:s is mainly because they don't want a fan making noise. If you still gonna use a fan then the WC is no use. A HDD does not put out that much heat.

Either you WC it or you AC it...

I'd say ditch the heatsink idea - using a heatercore or whatever is a much better solution to cool your water. I run 2x7200 RPM disks cooled by their sides only using water-cooling. When my temperature software / hardware was working, I was only getting a few degrees above water temperature - measurements taken from on the drive surface.

So basically, if you want to air cool them, you don't need heatsinks - just a fan works fine. If you want quieter operation, go for water-cooling in a foam-lined box.

If you want to cool two drives, get a bigger fan / make a duct to direct the air. Most disks are fine without any active cooling anyway (unless they're tightly packed together / in a confined space).

i do have heatercores, two of them, one external cooled by twin 80mm fans and another by dual 92mm fans. got them out of ford escorts.

the only reason the fan is there is because its modded with leds that flash to hdd activity. i was thinking that with the fan blowing over the heatsinks which were attached to the tubes and HDD,
the heat the HDD adds to the loop would be cancelled out.

An easier way to cancel the heat from the HDDs out is to not run water through the heatsink on them at all.

How fast are your HDDs anyway? My 7200 rpm S-ATAs only reach 29C with a single case fan at 7V blowing over them (for maybe 10 cfm). HDDs really don't need much cooling.
