      AM4 Socket Support   04/24/2017

      Due to technical issues, the topic on "AM4 Socket Support" has disappeared. We apologize for any inconvenience this has caused and we are trying our best to have this topic back up as soon as possible.   As we read in the topic, there is a lot of discussion going on when the new brackets will be arriving. We can tell you now that the brackets will be ready for pre-order on our CM Store EU tomorrow and will be ready for shipment around the 16th of May.   You can continue the discussion in this newly created topic:

Centurion CM590. Fully Ascendant Airflow

32 posts in this topic

Hello, I always wanted a case with full vertical airflow and the Silverstone Fortress FT02 have basically such sort of airflow but the I/O connectors of that case are at the top, and I wanted the I/O connectors to be closer to the bottom, this is the reason I took the Cooler-master Centurion CM590 and rotated 90 degrees the whole case to get the I/O connectors at the bottom. The other important modification was the ventilation inside the PSU to follow the same ascendant airflow of the case itself. To achieve that I just turned upside down the San-Ace 80x15mm fan of my PSU, finally I want to explain that the aim of this modification is to get a case featuring low back-pressure "Impedance" and therefore nearly all grills, the mesh and the filters have been removed to achieve the maximum available airflow speed, below I attached some photos.

PSU modification:
 
Hello, one very important modification for this project was the modification of the airflow inside the power supply. The original ATX power supply airflow has a fundamental flaw because was designed many years ago to pull warm air from inside the case.  To sort out this problem I just reverse upside-down the 80mm fan to allow the PSU to suck fresh air from outside the case. An extra modification made to reduce significantly the well known noise problem of the 80mm fans was to install a thin San-ace 80x80x15mm fan which has been made with low pitch blades. Also because of the higher efficiency PSU, the amount of cooling airflow needed by the PSU has been reduced. With this three modifications plus the fact that now the PSU is standing vertically at the bottom of the case, I have been able to achieve a fresh working and extremely quiet PSU. Below some images for better understanding the PSU reversed airflow
 
Notice: Because the PSU is vertically standing at the bottom of the case, the PCB inside the PSU is also in vertical position receiving vertical airflow, which is the best known way to cool down a PCB.

Motherboard Tray Modification:

 

Hello, A few details about the motherboard tray modification. Because the location of the cut-out to pass the PSU cables behind the mobo tray was not adecuate for my 18 cm long PSU, I decided to re-build the whole mobo-tray moving the cut-out to pass the cables and by the way using 2mm thick steel, below are shown some photos of the new and the original tray. I decided to use rubber stand-offs instead of the metal version because after turning the screws the metal stand-offs have a tendency to punch through the fibre glass.

Top Twins Exhaust 140mm Fans and Bracket:

 

Hello for the top 140mm exhaust fans I for the moment have chosen two (2)  Noise-blocker PK3, but some Yate-Loon D14SH-12 PWM are there already waiting for an eventual replacement, the Noctua 140mm 3000RPM Industrial fans draw 0,6-0,7 Amps each and if connected both simultaneously to the same motherboard connector which allow for (let say) 1 Amp max,  I think something can be damaged. I build a bracket for this twins 140mm exhaust fans which use seven of the available 5,25" front bays. I did this bracket because the original CM brackets available for this case only support 120mm fans, below some photos of the bracket with the 140mm fans and the red nose/spinners.
