some experiments and mistakes I unconsciously made after installing cooling fans within the case for the first time ever.
- I placed the
good looking side of both fans towards the exterior of the case, which means both fans were set for intake. I realised my mistake later. Even so, cooling was already much better than non cooling at all! Temps went from 88-89ºC to 81ºC, but the grill at the front of the case was exhausting a LOT of heat
.
-One of the fans had a MOLEX power connector as an accessory, so since I hadn't read the mobo manual, I used that connector. It works, but the mobo can't control the speed of the fan, so it was always running at an average speed.
- Later after reading the manual, I connected both fans to the System 1 and System 2 fan power connector (the mobo has only power connections for two fans). Thankfully my mobo has a BIOS feature called Smart Fan Control to control the fans so I don't need software like Speedfan and it does a great job.
- The fan with the best CFM was the one used as exhaust, while the other one was used for intake. I think it works better this way.
Now my PC can run demanding stuff without the GPU achieving dangerous temperatures of 88-89C -max is 90- and without sounding like a plane about to take off. Weather has been very rainy and cool these days where I live after the heatwave a week ago, but it doesn't matter, til yesterday I was experiencing high temps with demanding software.
