I upgrade a friends Acer Predator 3000 P03-650 case & heatsink a few days ago. Antec Flux Pro with Thermelright Phantom Spirit 120 EVO.
Just a slight upgrade in cooling, space and quality . I don't have figures of exact temps now but he was reporting CPU was easily 90-100 degrees in moderately warm UK climate. No major issues in the transfer over however
- The stock PSU cables for CPU are a bit short so I had to mount the PSU 90', cables pointing to the moterhboard panel. With the PSU mounted the standard way with cables pointing forward the 2 CPU cables could not reach the top of the motherboard. I would recommend having a pair of CPU extension cables if doing a case swap.
- The Acer RGB is 4 pin, so any addressable 3 pin RGB on the CPU fans would not function
- A front panel extension cable (individual cables) was required to convert the Antec front panel block to the old style individual two pin cables. I used power and reset
- 6 pin to SATA power cables were required to power the built in fan hub.
- USB-C and USB -3 on the case do not function due to lack of header connectors on the Acer
- Aerial on the M2 wifi card are hard mounted to the Acer case, so you'd need to buy new ones (or forcibly remove the ones in acer case)
- Stock backplate was glued on so take your time removing that, using a hairdryer to soften the glue will help.
Reported quieter and cooler running by a fair margin.
