Airflow will be part of it.Still on my stock cooler & i mean the psu fan is facing down to hsf..
I need more research to examine what the problem is before i decided to change something.. is it a cooler stock, a thermal paste, bios setting or anything else,
because it have a same temps even in my previous atx build.
If your stock cooler is sucking air from above and blowing downwards and your PSU is sucking air upwards and blowing out the back, they are fighting over air and basically will not cool at all.
These case were designed for 120mm or 140mm AIO coolers (though 140mm sort of no longer exist) however a HSF can be made to work. Generally speaking with this case you will need an SFX PSU if you are air cooling as the case is simply not designed for both an ATX supply and an air cooler. Option 2 below MIGHT work with an ATX no guarantees.
Commonly there are three ways to do airflow in a SG13:
- a low profile HSF blowing downwards and an SFX PSU sucking air from the outside of case so the air flow do not conflict. You will need at least 15mm clearance between the top of HSF and bottom of PSU. The front fan can be either exhaust or intake.
- a HSF with fan reversed and blowing upwards towards a PSU sucking air out of the case . You might get away with an ATX PSU with this arrangement. The front fan will need to be intake
- AIO as intake at front and exhausting via PSU sucking air out of the case
Basically if you want to air cool and also use the PSU to suck air out of the case you will need to flip the fan over on the HSF so it blows upwards towards the PSU instead of down towards the motherboard.
