Having had my main PC’s case hot to the touch last summer, I was wondering what was causing it. Components like CPU’s and graphics cards would need to generate a lot of heat to manage that. However, my main suspects are the hard drives in the machine: they do run hot after all and sit in a drive cradle connected directly to the case framework. As it happens, I was in Manchester’s branch of PC World yesterday and spotted Akasa hard drive coolers in stock for just £7.99 each. These dualfan units screw onto the base of your hard drive and their power connector can couple between a PATA power socket and a PSU power cable so that they can draw the power that they need without adding to case clutter. I bought two of the things and installed them; I’ll now see how they get on.
