CoolerMaster CM 690 II Advanced PC Case Review - CoolerMaster CM 690 II Advanced Review

Before we get onto this CoolerMaster’s insides though, let’s check out the cooling. The CM 690 II has two 140mm fans and a single 120mm fan already installed, which should be adequate for most setups. Just in case it’s not, there’s support for a total of ten 120mm or five 140mm fans, in addition to another two 80mm fans.

Below the 5.25in mesh drive covers at the case’s front is a single pre-installed 140mm fan that can be moved to cover any four of the available six internal 3.5in drive bays to suit your drive configuration. It has attractive blue backlighting that can be turned on or off with the aforementioned button. As this front fan is an intake, it features a removable dust filter. To clean the filter you can remove the entire front of the case, which simply comes off with a slight pull and clicks back in just as effortlessly.

Though the top 140mm fan blows air out, it too is protected by a removable filter (as is the entire mesh top of the case) to prevent dust getting in when the PC is not in use. You can install a second 140mm fan in front of it too, and again you can remove the entire top section to access the fan and filter.

Just above the final (120mm) fan at the back we have two rubber-edged holes for water cooling tubes of up to 2.5cm thick. All pre-installed fans have three-pin power connections to hook up to your motherboard and come with attached four-pin throughput adapters if you want to power them from the PSU.

Speaking of water-cooling, you can install a two-fan radiator either at the top or bottom of the case. The case’s bottom supports one 120mm fan ‘as is’, and removing the bottom section of the drive cage (leaving you with two usable bays) makes room for a second one. Plastic rivets for only one extra fan are provided.

On the right panel there’s provision for an 80mm fan to cool the motherboard below the CPU mounting area. The left panel has cut-outs for twin 120 or 140mm fans. The top one will give extra cooling directly above the CPU, while the bottom fan does the same for any graphics card(s) you might install. In addition to this there’s a dedicated graphics card support and cooling system which is included with the Advanced case, and we’ll cover it in more detail later on.
