Pc case fans troubleshooting

[Blash]

So I wasnt sure which tag was correct, however I have trouble with heat in my pc case and I was thinking of installing 2 additional exhaust fans at the top, however Im not sure how to supply them with power. I have my cpu fan and a back exhaust fan plugged into my motherboard and thats all of the connectors gone. I have 2 front sRGB fans but they are plugged directly into the psu, so theres that.

 

the fans would be noctua fans, the budget ones.

Please provide system specs. 

 

Most headers can provide up to 1A, although some pump and system headers can go higher. If your current fans as up to nearly 1A, your main choice will be to use a fan hub.

System specs you say.. 

Well I think you wanted to know my motherboard and the already attached fans.. so:

Asus A520-Plus Wifi and I have some sort of arctic fan, specifically ACFAN00118A 12 volts and 1.08 watts

 

whats a fan hub?

According to the Asus A520M-Plus Wifi page, you have two fan headers: one at the top right side of the mobo, and the other is on the left side right next to the end of the VRM heatsink. Since you haven't told me anything else about your PC, but most importantly the case, the number of fans, which are exhaust and which are int and where they're located, I'm limited in what I can tell you.

 

The fans you've given the model of is the Arctic P12. Based on the volts and watts, each uses .09A. Current specs for that fan say .16A, which could just mean that you have a different version of it. Assuming .09A, you could plug in 11 fans to one header. If it's actually .16A, you can use 6 per header. Either way, that's more than enough for the fans you have.

 

A fan hub is a simple device that allows you to plug in multiple fans to one header, similar to a splitter. The major difference is that there is at least a PCB with headers on it, if not other features, like individual control, power supplied from the PSU, a USB cable to control the hub via software, etc., such as the one below. There are many different varieties of fan repeaters, hubs and controllers, including for lighting.

Hey, I see I failed to explain it. I have a simple build, the motherboard you know, it hosts 16 gb of ddr4 ram, an ryzen 3 3100 with the stock cooler, a amd rx 580 8gb, a 750 watt psu with modular cables and an m.2 ssd 500gb from crucial. Its a mars gaming case, I got it from amazon after looking for a decent and budget case. It has a mesh front, a mesh top, a (what I believe to be) clear plastic side panel, a solid cover on the other side, no vent holes on the bottom and a standard back with an opening for a fan. The case came with two srgb fans which plug directly into the psu, I plugged my cpu and the arctic fan into the motherboard. The arctic fan is positioned at the back as exhaust. The airflow is pretty linear from front, where the two fans from the case are situated, to the back, where the single arctic fan is exhausting the warm air. I want to improve thermals at least a little by adding a fan or two more since I get the feeling that warm air is not getting out fast enough. I am well aware of needing a positive air pressure inside the case, so I have been considering simply replacing the front panel fans because they dont seem to be all too powerful. This was I would have better everything at the cost of thinkering. Otherwise I want to add a fan to exhaust the heat at the top. 

 

I live in germany, however, would you mind linking me a decent fan hub. The ones I find on amazon are all the simplest pcb with extra connectors. Those seem untrustworthy, but I could be wrong. I built my pc myself, I would like to add to it where possible. On top of that when the Intel B580 comes out, I will be upgrading to that, so if thats relevant at all, there you go.

a fan hub just take extra power from the psu to power the fans as pwm fans use 12v all the time. the pwm is gotten from the fan header by passing the 1 amp limit on the mb header. that it all it dose.

I see. Well then I think Ill buy one if I can find a trusted and good quality one. Thank you

hold on i was drunk when saying part of that my bad ill re wright what i was thinking...

 

so a fan hub is like a splitor but insted of a splitor cable its on a pcb. hubs come in all sizes with up to 10 fans. some get power from the psu by a molex connetor, some by sata power.

 

why use a hub? well a mother bord header has a limit of 1 amp for power so if you got fans more then that it wont work.

 

pwm fans run at 12v all the time so getting power from from the psu is better and cleans up the cables too. the pwm gos to one of the mb headers and sends pwm to the hub and all fans on the hub fallow that pwm. normally like 50% on and 50% off but you can change that in the bios. hooking different rpm fans to the hub will all run at different speeds based of whats its set at. so say you got a 1000 rpm fan and its at 50% thats 500 rpm but another fan you have say 1200 rpm the fan will run at 600 rpm. not much different but can if you have way different rpms.

 

most people set fans quiet at idel and ramp up when gaming.

 

im tired and its at night hope i wright it right this time?

Your idea of better fans is warranted. Are you noise-averse? You could go with the Arctic P12 Max. There are stronger fans, most of which cost more.

Hey yeah thanks for the information haha! Honestly I just want to run around 4 fans from the same connector. Two intake and two exhaust. Also no rgb is needed cus I only care about performance. 

Thank you.

Cost isnt too much of an issue. I do like quiet operations though. More so because I tend to enjoy music and I work daily with my pc because of my studies. Ill definetly check out the Arctic P12 Max. Id still need a decent fan hub but otherwise fans would be set so far. 

Thank you
