Hey all. The system I'm getting ready to put together for myself is going to have two 74 GB raptors running RAID 0. The only thing I'm a little concerned about is the heat. Can someone please recommend a pair of hdd coolers. I would like to keep it on the quiet side so something internal would be preferred. I've seen the vantec's at new egg but would like to hear from some people with experience.

THANKS
 
nothing that i know of that will keep the raptor especially cool and quiet. zalmans heatpipe hard drive cooler is an option although its not great. this quote is from silentpcreview at the bottom of the page...
Zalman's NP Heatpipe HDD Cooler ZM-2HC1 is recommended by some hardware reviewers as a hard drive decouple mounting that helps reduce noise. My firsthand experience is not the same at all. It may help a bit in cooling, but only if there is some airflow in the CD bays to begin with, and it does almost nothing for noise, because the rubber used in the four cylinders that are meant to be shock absorbers are just way too hard. There are some things Zalman does really well -- coolers in general. There are other things they seem to do badly, fans being one of them; this HDD cooler can be added to that bad list.

If you get a good case, with excellent cooling, you don't need anything special in terms of cooling. My Raptors stay a nice temp, and don't feel warm to the touch.
 
I had a drive bay that I could put an 80mm fan in.

So, I just got a real quiet fan to throw in there and it keeps them basically at ambient temps. As in they feel the same temp as the rest of my case does.

I didn't have the fan connected for about a day running and they really even didnt get that hot anyway.

But, the closer to ambient temp hard drives usually last longer =P
 
You wont need coolers for these drives. They dont get that hot. They actually are suppost to be cooler then the 36GB raptors which dont get very hot ither. All you need is a good front case fan blowing over them. But even if you didn't have that and had good airflow in your case they would be fine. They really dont get much hotter then normal 7200 rpm drives.

Anything under 15,000 rpm doesn't need a HDD cooler. Just try and leave a slot between the two of them so plenty of air can get through.
 
while they may not get all that hot....

like any other mechnical device (or even semiconductors)
they will benefit from cooling, in very rough terms strictly as a rule of thumb

Each 10°C (18°F) temperature rise reduces component life by 50%.
Conversely, each 10°C (18°F) temperature reduction increases component life by 100%.
the Arrhenius equation

the most effective HDD coolers are those that both increase the interface for cooling (by adding a heatsink) and increase the airflow if the HDD isnt already in a good airstream (I use Rackmount cases where for instance I have 3 x80mm fan in the front door and 3 x 120MM Fans in the middle of the case, the HDDs are inbetween these, but then the linear airflow through a rackmount is anything but typical in a desktop case.

and finally lower your ambient temperature, the thermal resistance (C\W) of any heatsink (or just the HDD case itself) increases in effiecency with a lower ambient temperature
General Heat Transfer Guide

my cases are force fed AC air

this is a fairly representative selection of what is available

I like the crossflow fan in the Vantec Vortex VTX-CO1 and since its not a swap bay enclsure any HDD you get in the future will work
(SCSI SATA PATA even Fibre Channel :p )
and there is even probably room for a thin heatsink to be mounted to the top of the drive as well,
though most would consider that overkill
