Keeping Your Hard Drives & Computer Cool
The warmest room by far in most homes is the home office, mainly because that’s where the computer and the hard drives live. Any creative will generate loads of data (pictures, video or audio) which means loads of hard drives for storage and backup. Even though some external hard drives have fans to keep things cool, once these pile up, pockets of hot air form and have an effect on both the active (fan) and passive (heatsink) cooling of hard drives. Excess heat can result in hard drive failure and on computers erratic behaviour at best or failure of internal components at worst.
Server rooms in offices have specific air-conditioning installed to keep the storage arrays cool, but alas most of us won’t be in a position to do that. Next best thing is to move the hot air away from the drives and also to cool the air falling upon and into them.
A very simple and cheap solution is to install a powered USB hub and plug in some USB fans. These will cool down the air and also move the air around. Simple, cheap, easy and effective.
Another use for the simple USB fan is to have it cool down the air that’s sucked into your computer by it’s own internal cooling fan. By cooling the air outside the computer, the computer’s internal cooling system has a more effective job of keeping the CPU, GPU and internal hard drives cool. Incidentally, having a fan blow cooler air towards the air intake on your laptop will have the same effect (on Apple MacBooks it’s the hinge between the screen and keyboard. On PCs it’s sometimes the same place and sometimes on one of the sides).
Naturally, on hot days, the same technology can be used to cool you down too!
