Passively Cooled Gaming PC

[Dregntael]

Hello,

I've been reading some of the (very good) articles on this site, but I could still use some advice for our new system.

We're planning to build a gaming PC with only passive cooling. I've been looking aroud here and there and this is what I found:

- CPU: AMD Phenom II X3 705e (only 65 watt)
- CPU Cooler: Cooler Master Hyper Z600 (no fans)

- GPU: Club 3D Radeon HD 5750 Noiseless Edition 1GB

- Case: Cooler Master Sileo 500
- Fans: 2x Noctua NF-S12B FLX 120mm fans
- PSU: SilverStone NightJar 450W

- Mainboard: MSI 770-C45
- HDD: Western Digital Caviar GP 1.5TB
- RAM: OCZ Gold XTC 4GB DDR3-1066 CL7 kit
- Optical drive: Optiarc AD-7240S-0B

The only active cooling comes from the very quiet 120mm noctua fans. I've read that the CM Z600 in passive mode should be able to cool the 705e.

What I don't know is whether the cooling and airflow will be enough to keep everything from overheating. Any other advice is welcome too.

Thanks for your help,

Hello, welcome to the forum!

To increase effectiveness of the Cooler, I suggest you will duct it to the rear exhaust- This will quarantee the cooling capacity of the CPU

Now 5750 can run pretty hot passively, so do think getting slowspeed 500-800rpm fan and attach it on cooler if necessary.

With lower power components designed for passive operation, adding even a single fan should be enough to ensure that your temps are low (enough).

Also, consider running the fans at a lower speed (maybe with just 5V) for more quiet operation.

You may not need a duct, but a motherboard that has the socket closest to the rear is best. If the heatsink is at least 1" from the rear fan, good passive cooling is possible.
