I recently bought my sg13. My pc build: ryzen 5 3600, 2x8 3200mhz, rx 570, 450W atx psu, 1HDD, 1 SSD..
I have no change the settings on Bios except XMP profile. The PSU orientation is upside down.
And then i realized my cpu temp reach 95C on gaming & +-60C on idle.. theres any wrong?

Idk its a problem of case airflow or ryzen 3600 itself, because in previous atx build with 3 fans, the ryzen still reach about 89C

What cooler ? With an ATX sized supply the case is really mainly suited to an AIO water cooler. Also what do you mean by PSU is upside down ?

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.

Airflow will be part of it.

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:

1. 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.
2. 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
3. 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.

Man, your explanation really insight me!
Im not really getting into aio, considering im plan to having mobility with this case (unless i know how to maintenance aio), so im going to option 1 & 2.

1. If im using atx, will it still work? I think this is a short plan to me
2. If i choose it, What the best reversed hsf out there? Im really newbie about this. I just research and found Id cooling is 47, but im not sure

For now im using arctic p14 pwm as front fan & planning use 120mm fans because it block my drive cage & pushing my gpu board.
What is your recommend for 120mm fan? I know noctua is the best, but if i can get another fan with similar performance but cheaper, ill not buy noctua. But if noctua is the mandatory choice, what is better, nf f12 or a12?

Thanks anyway

With an ATX I would go for option 2 using a NH-L12 like Devoker recommends, with the fan under the heatsink mounted so it blows air upwards towards the PSU.

Mount the ATX PSU so that is sucking the hot air from the HSF out of the case.

The front fan can be any 120mm that has good cfm and should be an intake blowing air towards the CPU and HSF, you probably should go for a high flow fan rather than high pressure. Check what ones are available in your price range and look up reviews for them.

Thanks man, but the nh l12s height is 70mm and cooler clearance in SG13 is just 61mm (with atx)
Will it fit?

NH-L12

The NH-L12 is a low-profile quiet cooler designed for use in small form factor cases and HTPC environments. With its flexible NF-F12 (120mm) / NF-B9 (92mm) dual PWM fan setup, the NH-L12 can be configured either for full performance in dual fan mode or extra-low profile (66mm) with the top fan...

This might be the best to use with an atx psu.

Thank you! But sg13 cooler clearance 61mm isnt right?

OK, probably not and the other common choice, Big Shuriken 3, is only 1 mm shorter so it is out as well.

Unfortunately this case was designed around using an AIO if you fit an ATX supply so your cooler options (unless you seriously hack the case around and move the ATX PSU to the front) are limited.

Try playing with the airlflow and reversing the fan on your existing heatsink to blow towards the PSU.

If that does not work out, the best options in order of least cost first:

1. give up on sg13, sell it and put cash towards a slightly larger case
2. give up on HSF and buy a 120mm AIO
3. give up on ATX and buy a SFX supply and NHL-12S

Option 2 is probably the optimal one. Note that really big 120 mm AIOs like the H80 will not fit with two 25mm fans mounted without some hacking of the front case.

Yes, finally i cant being hard for this problem 😅 i decided to buy AIO H60/Frostflow 120 due to my budget
I hope it will easy for maintenance..
Btw, thx man for all your help. I really appreciate it
