Can anyone recommend what case fans/exit fan I should get for a PowerSpec G433 PC? Also where do I disconnect the fans? The motherboard is a ASRock Z390 Pro4
What's the problem with the fans it came with? I don't understand why you're asking so it's hard to think of an answer.
The fans probably plug in to the fan headers on the motherboard. Any 4 pin PWM fans will work as replacements.
Personally love the Arctic Cooling P12: https://www.microcenter.com/product/600913/arctic-cooling-p12-fluid-dynamic-bearing-120mm-case-fan
Excellent fan for the price. You can buy them in packs, and there is an RGB version.
As for the fans, you'll have two cables for each. The RGB cable should go into a splitter, and to the Cooler master RGB controller inside the chassis. The fan power would go to the board. The board has three different chassis fan headers.
