Re: Looking for a good 8cm fan, operating at 5v...

Thanks for the suggestions. Unfortunately, both of those fans are 25mm deep -- the 15mm depth is a serious limitation. So far I've only found one low-noise 80x15mm fan that claims to operate down to 5v (although it needs a starting voltage of 6v): Noiseblocker-NB-BlacksilentPRO-PCP.

Looking for a good 8cm fan, operating at 5v...

An unusual query perhaps: I have started using an Akasa Aries laptop cooler -- a simple aluminium laptop stand with an 8cm fan attached, powered by USB. The stand is fine, and the simple mechanism of a slab of aluminium and space under the laptop does aid cooling. But the problem is that the stock f...

The mystery slot is a half-height, half-length 16x PCIe slot. The 1x slot is also half-height and half-length.

Re: HP MicroServer

You claim that many SMBs do not have the skills to run a Linux server but that's not the main reason organizations pay for Windows servers. Running a Linux server is very easy and organizations which do not have this basic skill should be outsourcing their IT! Many small businesses (in the 5-20 emp...

Re: HP MicroServer

For info: just carried out fan replacement successfully using the guide in the review (camlin's pinout). I used an Akasa Apache. This has a max speed of 1300RPM, but a minimum of 600RPM, which I guess is the important thing here (to prevent power down).

Re: HP MicroServer

Thanks for the review, particularly the step-by-step guide to fan replacement.

One query. Your picture of the modded fan makes it clear that you are using camlin's pinout guide. However the HP pinout info at the beginning of the guide is a different pinout again, and that's a bit confusing.

So what did you do? Do you have any suggestions for this thread? -- http://www.silentpcreview.com/forums/viewtopic.php?t=60142 The first decision I made was that using eight drives was limiting my options too much, so I bought some bigger drives and reduced the overall number to six. Then I decided...

@JamieG, @Qianlong -- thank you both. The more I have read here in the last day or two, the more I realise that suspending the discs is the only real answer, and long towers full of 5.25 bays such as the ones you suggest are probably the best route to take. I'll investigate further.

Thank you for the responses. @faugusztin - I did read the SPCR review of the Fractal Design Define R2 and for some reason it put me off. I'll go back and read it again. @speedkar9 - I do like the idea of suspending all the discs. I use Sonatas for my desktop PCs, with all discs suspended, and it doe...

Case to minimise noise/vibration from eight hard drives?

I have a home-built NAS that has been running happily for years. It used to live in a cupboard but since moving house it's had to live in my study, and I've realised that the one mistake I made when building the NAS was to use a cheap case without any option for damping for the hard drives. Even add...
