The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.

120mm Silverstone SST-FW121 FW Series PWM Fan is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Thin/Slim (15mm) fan! Well, as my 8 core AMD got a tad warm on occasion (even with many fans in my case) I decided to hack a hole in my computer case and install a fan below the CPU. My case was apt to get quite warm in that area so I decided a fan was needed. Because of the fan's location I needed a low profile one and I also needed it to be PWM (my last fan wasn't). Enter the "120MM Silverstone SST-FW121 Series PWM fan". If I'm really honest this fan may well not have been my first choice but my options were limited, as a normal 25mm fan would not have fitted and Scan don't sell a whole lot of 120mm fans that are only 15mm thick. Not too keen on the colour but as it's behind a grill one can hardly see it now.... What can I say? It does the job, my (CPU) temps are a few degrees lower than they were and my computer remains quiet, the two main reasons I bought it.... :)
