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.

Rated 4 out of 5 by from Does what it says on the tin I bought these for mine and my brother to help with the air flow of the machine and they are working perfectly. For my case I required a different type of screw to fix them but luckily I had some, they are slightly louder than expected but I did stick 3 of them in my case.

Rated 5 out of 5 by from Wind Tunnel cooling! Aside the sound which doesn't bother me as I have good speakers these fans are awesome, i can see the dust on the filters more showing how much air they pump through my system. Good value for great fans. And pretty lights oooo.

Rated 4 out of 5 by from Good but not quiet I bought a few of these to fit in my case they are very good at keeping my PC cool but they are really loud I am not sure if it is because I put them in properly but they are really loud.

Rated 4 out of 5 by from Optimised for airflow The normal full running speed of this fan is 2000 rpm, so it is not really intended to be quiet. If your motherboard allows, or if you use it with a fan controller, you can reduce the speed and reduce the overall noise slightly. The airflow is excellent and curved fan blades in combination with the bright LEDs produces a pleasing lighting effect.

Rated 1 out of 5 by from So loud! This fan looks nice & the leds are pretty enough but the fan is so loud! If you care at all about a quiet PC then do not buy this fan, I was really disappointed the second I powered the PC on. There are MUCH better fans for both airflow & noise so avoid this unless noise isn't a factor for you.

Rated 1 out of 5 by from very loud i purchased 4 of these fans expecting a good looking and quiet operation but i got neater, the LED lights are pointless and do not illuminate very well and even at 7 volt RPM are still horribly loud, so overall im very unhappy with this purchase and i would have returned them but my parents broke the boxes
