Date Issued: 20th Oct 2008

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.

Date Issued: 19th Jun 2008

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.

be quiet! Dark Base 900, Orange, Full Tower Computer Chassis, E-ATX to Mini ITX, with 3x 140mm Silent Wings Fan is rated 4.5 out of 5 by 4.
Rated 4 out of 5 by from Innovative, very modular and well though out case, just bin the fans. A one size fits all case. This case is very modular, and can be call a one size fits all. All the major parts can be shifted around to your desire. I changed my case as I couldn't fit the huge radiator with the motherboard cables. The motherboard height can be changed or even flipped round. The PSU can be moved too. Nearly any fitting problem can be solved. The build quality is great. The fans are all hidden. The top fans are hidden underneath a panel with vents for air. The side panel fans are brilliantly though out. My old case, you only had two options. Fully covered or not. Instead you can have the cover panel raised. Dampens the sound a bit and still provides airflow. Going onto to dampening. This case is very effective. It is all over and the door actually does block sound, unlike my very reputable Corsair case. All fan intakes have filters as you would expect for this price point. The looks are smart, jet black with touches of oranges. Works really, well, with a nice balanced look. My only complaint are the fans provided. These fans are too optimised for sound. My computer is overclocked but with fans at full speed, my computer was crashing. When I checked the airflow of the fans, it was pathetic. I replaced them with my previous Corsair brands and made a shocking difference. The reviews on this case mention how the components run hotter than most cases. Well the terrible fans are the reason. Replace them and you've got a whisper quiet, cool case.

Rated 5 out of 5 by from Awesome Modular case. Spacious, easy to install everything. I had to transplant my psu which went smooth. Plenty of space for cabling, also very easy cabling and lots of different options. Not that you are forced to squeeze you cable in a certain way to get to the top part of your motherboard. There are a couple ways to approach, plenty of intermediate holes and cable support. My previous case was an antec 180 which are very solid cases. But I found this one to be much better. The on button being on the top front side is very handy too, don't have to lean over, it can be switched on comfortably without hassle. Small but great. Another small bonus, its completely modular, so if you ever in many decades from now need to get rid of the more hassle of having a case that you can't dispose easily. This one disassembles completely due to its modularity.

Rated 4 out of 5 by from Good case but surprised by some bits. The back of the case has no noise protection seating the power back forward from the back helps and am not sure how well it will do with dust. Still a bit early to tell but so far it is pretty good.
