A high proportion of noise created by PCs comes from the hard drive(s). This is because the magnetic platters in the hard drive spin constantly at high speed. In addition, the heads moving back and forth across the platters cause "clicking" noises every time files are accessed by the operating system.

Much research and development has been done by drive manufacturers in recent years to try to make hard drives quieter, but despite this, the noise most drives make is still very noticeable and distracting, even when using hard drives which are specifically marketed as being supposedly "quiet". The obvious solution is to enclose the drive in an acoustic sleeve and this is how SilentDrive™ works.

However, the typical problem associated with acoustic enclosures is cooling - excessive heat is not healthy for a hard drive. The SilentDrive™ fully addresses this issue by having two aluminium "cold plates" which cover both the top and the bottom of the drive and conduct unwanted heat safely away into the surrounding air and chassis mountings.

• Reduces hard drive noise by over 90%

• Easily fits into new or existing computer

• Accepts all 1" high 3.5" drives

• Fits into a standard 5.25" (CDROM-sized) drive bay

• No special installation tools required

• Has cut-outs for breather hole, power, and IDE/SCSI ribbon cables

• Does not affect drive performance

• Gives extra shock protection during PC transit

• Sits behind the bay blanking plate, so does not affect aesthetics

• Lasts virtually forever! Buy one and transfer it every time you change your PC.

It has been proven that the SilentDrive™ has the ability to work safely with hard drives which dissipate up to around 6.8 watts of heat, keeping the running temperature under the 55°C maximum which is specified by most hard drive manufacturers. The "heat dissipation at idle" and maximum running temperature can easily be checked by looking at the specification sheet for your individual hard drive.

Because the heat generated by a drive is related to the spindle speed, most drives with a spindle speed of 7,200 rpm (revolutions per minute) or less are compatible. Generally speaking, if your drive runs at 10,000 or 15,000 rpm then unfortunately it will run too hot to be enclosed.
