Chassis Airflow
Chassis Airflow
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.

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 PRO 900, Silver, Full Tower Computer Chassis, E-ATX to mITX, with Window, 3x 140mm Silent Wings Fans is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from Great Case! This case is absolutely brilliant. I bought this case following my previous case having a fan controller molex failure, I'd highly recommend this case it's silent, very smart looking and very easy to install components with it being fully modular. 2 things bug me with this case however for the premium price paid. 1. No PSU shield included, which is small, but Be Quiet! don't sell them either, currently only one seller I can see for £70! 2. The screws on the case themselves to free up PCI-E shielding on the rear are very poor for the pricing, one shield I cannot remove as the screws simply disintegrated/threaded when tried to remove.

Rated 5 out of 5 by from Quite pricey, but definitely does the trick. This case is massive, feels very well made and looks great. Most importantly, for me, this case is almost totally silent - the be quiet! fans are very good and the sound insulation helps a great deal. My only issue is that the screws holding in the PSU enclosure were far too tight - to such an extent that I'm pretty sure I have rendered them unusable trying to remove them and had to find a workaround (May well just be my own incompetence, mind). Everything seems nice and easy to sort out and there's plenty of room inside for pretty much anything you want to do. The LED strips are also a nice touch and I even use the wireless charging pad on top for my phone. My only problem is that if you ever try to move the case you will have to secure the front door or it will swing open whenever you try to do anything. I love this thing, it's ridiculous.
