Whoops, completely forgot about that... Corsair TX650M, 650W. Edited and added it to the post.

My setup, built in May of last year (all new): CPU: R5 3600 GPU: XFX RX 590 8GB PSU: Corsair TX650M (650W) RAM: G.Skill Ripjaws V 3200MHz, 2x8GB, CL16 Mobo: Gigabyte B450M DS3H SSD: WD Blye 500 GB m.2 SATA III So here's my situation. Firstly, when my card was new, everything worked fine but in a few rare games I stopped getting video output seemingly out of nowhere, maybe when I pushed it too much. A machine reset is necessary, but it comes back to normal afterwards. Now, almost an year later, it has "evolved". Every 2 days, when I boot my machine, I will get half the framerate that is normal. Games run fine for a while. If I push it too much, I stop getting video output and I need to reset. However, after the reset, Windows will be back to using the default driver and I will get the awful resolution and all that. I actually have to reinstall the driver for everything to work again.. For 2 days until it happens again. Now, today, it was kinda weird. Seemed to have "evolved" again. Straight up black screen before even logging in to Windows. Moving my mouse literally got me audible "boops"??? Replugging the HDMI cable made it boop too. It seemed to be some indicator of user input or something? Resetting the machien and I was back to the usual Windows generic driver and that's where I am right now. Went to Device Manager and checked my GPU... Seemed to be "disabled". Enabling it threw a warning sign on it and I got a popup from the AMD software claiming an error has occurred. When reinstalling I had not actually used DDU but I will now because this is starting to be too much. Should I consider RMAing my card? Between the first and second "evolutions" I actually wiped my disk and reinstalled Windows, so that might not be it. I initially gave this the benefit of the doubt but I'm starting to get fed up with it, not because of the time it takes to reinstall the driver but because I have no idea what the problem is or where to even start. This was my first build so I don't have any other spare parts to test.

It appears I, as usual, couldn't word it properly on the first try... Ugh. There is a CPU input that I am using for the CPU header. The question is about how I should use the one other header. What I take from your reply is that I should use the VRM as input for all case fans? Guess it makes sense. Is it the VSOC MOS or VRM MOS? I assume the latter, but who knows. This motherboard (Gigabyte B450M DS3H) doesn't have a lot of documentation.

My motherboard only has 2 fan headers, one for CPU and the other for whatever. I got a fan hub and a total of 4 fans will be connected to this hub (2x 140mm input, 2x 120mm exhaust). The temperatures that can be used as inputs are Chipset, VRM MOS, VSOC MOS and System 1, on top of an adjustable fan curve. (I assume System 1 is an average or something, I have no clue). Which do I pick to keep this PC as cool as possible? I don't give a crap about noise, as long as there is noise only when under load.

HWiNFO reports the same temperatures. Perhaps I shouldn't have worried if it's normal. Thanks.

I started noticing this because the fan keeps revving up and down, and then I checked HWMonitor, and the CPU (Ryzen 5 3600) keep jumping 10ºC out of nowhere. It then cools down those degrees, and jumps again. What confuses me more is that it only happens on the "Balanced" and "High Perfomance" power plans; with "Power Saver" it doesn't happen. I'm using the stock cooler. According to a bit of research it's normal because Windows, but it is really weird.

That's great actually, it should work. Thank you so much.

Ideally I would be able to do that... But it appears I didn't word myself before properly, sorry. This motherboard only has 2 total fan headers: one for the CPU and one for other fans. So I would probably need a hub since there is no cable that will go from the rear to the front...

Portugal, found a store selling them for 7.90€ but it's out of stock, will have to wait haha. Do you happen to know what is the maximum number of fans connected like this, and if I can connect a different size? Asking because the rear fan I have is 120mm and 3 pin, so this will get confusing to manage.

That wasn't exactly clear in the description I say, so thanks a lot. That seems like a great solution actually. Will have to find some store that sells those where I am. Do you know how many can be daisy chained?

I'm a bit confused. Are the fans daisy-chained, or would it require a splitter? Sorry, bit of a noob, what exactly does that mean and how that work?

I'm using a CoolerMaster MasterBox Q300L and it came with a rear 3 pin fan. No idea what its specs are. Since right now the airflow is terrible for sure, I'm planning on buying two NF-P14S redux-1200 (also 3 pin fans) from Noctua. They for sure will have different specs from the included fan. My motherboard only has 2 fan headers, including the CPU's, so I'll need a fan hub too, and was looking at the DeepCool FH-10. My question is, how would this be plugged in? Like, since the motherboard will only read one fan and the others will do whatever that specific one does, will different specs fuck anything up? Or can I just plug them however I want and it'll just work? Sorry for the dumb question and meh English.

I checked and I think it seems to be an "inline interactive" UPS, so to my understanding of everyone's useful insight, I should be perfectly fine. Please correct me if I'm wrong. Thanks everyone for the useful information.

Not the other guy but your explanation seems pretty good. But what does it mean if nothing shut down by itself? That seems pretty weird

The PC did not shut down by itself, it was me as I got scared... But thanks a lot for relieving me. I don't think I would be able to sleep if I damage by first rig less than a day after building it...
