[SOLVED] Adding a secondary fan to DeepCool Gammaxx GTE

Hi guys. I bought a Gammaxx GTE (http://www.deepcool.com/product/cpucooler/2018-08/7_9272.shtml) some months ago to replace the stock cooler of my Ryzen 5 3600. It was a budget solution (didn't have much to choose from where I live, I would have loved to buy a Noctua NH-D14) but it worked really well.

Since summer is around the corner, and last week we had a max temp. of around 40°C after midday, I wanted to add a seconday fan to my Gammaxx, make it push-pull configuration.

The cooler came with extra fan clips and I have an extra 120mm Cougar Vortex PWM fan (https://www.cougargaming.com/fileadmin/downloads/COUGAR VORTEX PWM.pdf).

On pappers (specs on the links) it seems the Cougar fan is stronger than the one that came on the Gammaxx, so am I right to use the Courgar as the Pull fan?

---- fresh air front of the case ---> Gammaxx Fan ----> Heatsink ---> Courgar fan ---- hot air to rear of the case ---> exhaust case fan

Forgot to mention, If this sounds ok Im getting a pwm fan splitter tomorrow.

Thanks!
