[SOLVED] Cooling questions (Ryzen, RX580, 3 fan case)

[rootordie]

Evening all.

So I finally built my first PC (yay) and it actually booted 1st try which shocked me. This was the full build:
Ryzen 5 2600 (https://www.amazon.com/dp/B07B41WS48/?tag=pcpapi-20)
Asrock B450 Pro4 (https://www.newegg.com/Product/Product.aspx?Item=N82E16813157841&ignorebbr=1&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=)
Corsair Vengeance LPX 8GB RAM (https://www.amazon.com/dp/B01ARHBBPS/?tag=pcpapi-20)
Kinston A400 240GB SSD (https://www.amazon.com/dp/B01N5IB20Q/?tag=pcpapi-20)
WD Blue 1TB HDD (https://www.amazon.com/dp/B0088PUEPK/?tag=pcpapi-20)
MSI Armor 8GB OC RX580 (https://www.newegg.com/Product/Product.aspx?Item=N82E16814137118&ignorebbr=1&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=)
Rosewill Challenger-S Case (https://www.amazon.com/dp/B00BV31QU8/?tag=pcpapi-20)
Corsair CX650 PSU (https://www.amazon.com/dp/B01MRW2K7E/?tag=pcpapi-20)

Anyway, I was installing drivers and software on Windows 10 after the build (and testing the DVD drive I also took from a thrift store PC) and I noticed the internal temperatures seemed like they were running high (at least it seemed like it to me). The CPU and mobo temps were steady at about 85 degrees Fahrenheit while the GPU (which I didn't think was under any load at all) was as high as 122 degrees Fahrenheit. Today I tested again and noted the CPU and mobo were a bit cooler at (79 for CPU and 84 for mobo). I also set my GPU fans manually to about 40 in Afterburner and got it down to 84 degrees.
Are these temps normal? I don't smell anything burning inside the case, and I can feel air moving from the intake and exhaust fans. The case came with two intake fans in the front and one exhaust fan at the back, but the lower exhaust fans is blocked by the hard drive bays on the bottom. I'm also using the stock AMD cooler (Wraith Stealth). The PSU is mounted with the fan facing up into the case so I wondered if the high temps from the GPU were being caused by the PSU blowing hot air straight up at the GPU.
What should I do here? I'm a brand-new builder, with no knowledge of how to proceed. Should I be using software to change my fan speeds (case fans, CPU cooler fan or GPU fans)? I was also looking at buying two 140mm fans to mount on the side of my case, blowing straight down onto the mobo, would that be a good choice (they'd have to be connected to the PSU directly since I only have three fan headers)? Anything else I should try, or any feedback on my build?

Sorry for the overload of info, any help would be appreciated.

Thanks.

Those temperatures aren't high at all. The Radeon RX 500 series is good up to about 80 to 90 Celsius (176-194 Fahrenheit).

You should run a benchmark like 3DMark and see what your GPU temperature is under a full load.

Meanwhile, the Ryzen 5 2600 is rated for 95 Celsius (203 Fahrenheit).

With the CPU, you should also run a benchmark or burn-in program that will subject the the CPU to a full load, and see what temperature it reaches.

Also, most PSU fans function as exhaust, not intake. I suspect that the PSU is sucking air away from the GPU, not blowing air onto the GPU. But maybe your PSU is different? Hold a piece of paper near the rear PSU fan, outside your case, and see if the piece of paper gets blown away or sucked towards the PSU.

In any case, though, your temps are just fine.

Thanks for the reply. The only reason I was worried is that I saw a few reviews on newegg for the particular RX 580 that I've got and many of them said that the card tends to run really hot. I would assume that that would reduce the lifespan of the card and computer overall. I thought it was odd that the thing was reaching 122 without me even playing a game or doing anything intense, graphics-wise.

You were right about the PSU, thanks for the info. Do you think it's worth me getting any extra case fans? I just want to be sure this PC and GPU will last..
