I accept that, but as a precautionary measure to extend reliable lifespan I am happy to add extra cooling; the fan units are readily available at computer fairs for that purpose and quite cheap, so why not?
In my defence may I point out that before retirement I was an Electronics/Radio Design Engineer with responsibility for military spec. equipment as well as commercial, and the case and operating temperature requirements of the MOD were very stringent because they wanted ultra-reliability...before it got blown up, anyway!

Ron - the fans you buy at said fairs will be the cheapest, shittiest fans known to man, and will probably be less reliable than the disks they protect .

TBH, unlike 10 years ago, drives can run much hotter without significant reduction in reliability, partly because they are more power efficient and generate less heat, but also they are designed that way to reduce cooling requirements. Gone are the days when data centres had to be at 20C, thank god


I good case design should be able to get sufficient airflow over the components that need cooling in a most passive way, with one or 2 fans providing enough airflow over PSUs, CPUs, GPUs, RAM, Comms controllers and disks. This is the current design philosophy by the likes of Intel and AMD, and what they expect system designers to follow (which the premium brands do - its the self build/back street PC shops that don't). Its advantages are clear - reliability, lower noise, more energy efficient.  Adding additional fans can disturb this airflow, rendering the whole system sub standard.


Hope that clarifies

Tee hee - my drives ARE old! Ten years? Probably, as are the cooling fans, so they have lasted well too, for cheapies.
I'm not disagreeing with you, but I go with what works for me.
I cannot comment on your airflow argument because I'm running my PC without a side panel, as I do tend to play about with it, so that would be a major variation on the design spec!

In general, adding cooling fans to specific components is a bad idea.  If the chassis doesn't have a decent throughput of air, you are simply blowing hot air around.

Back in 'the day' advanced desktop systems had a fan at the front of the chassis drawing air in and the PSU fan was the exhaust.

Nowadays with active heatsinks on everything, the airflow is a complete balls-up.  Not to mention that everyone wants a tiny little machine with masses of power.

Go back to the Full ATX stuff with fans larger than the engines on a 747.

All server racks tend to be in Air Conditioned rooms not just for temperature reasons, but to keep moisture to a minimum also.

It's truly amazing how quickly technology moves on!

Ah, yes, a modern PC running at full chat is liable to grumble if running with the side off

Good job nothing important was hosted there.

Just to update.  It seems that the cble was at fault.  Replaced it along with a rebuild (it was time plus I want to play a little with Security Onion in a VM) and it's like having a new macine

never seen a hitachi fail


fujitsu : rare..


western digital : long years ago was very reliable but not now..


seagate : high percent failure really

Have seen all of those fail in the past.

Long and short of it is that ANY electro-mechanical device can fail at ANY point in it's lifespan.
Am currently running a Crucial C300 256 GB SSD which was fitted in April 2011 and continues to work without issue.
Cost £400 back then, but that was when SSD was new technology and can probably be obtained for less than half that price now.

If you want a drive that can be really worked, go for "enterprise" rated disks.

thats correct .. but ...........  statistics says that some are more prone...

Please don't mention statistics, Cem, my blood pressure won't stand it. I/you can make statistics say anything we want them to say.
