New fans not working

[dizmo]

I installed some P14 PWM PST fans onto a CLC280. Plugged them into the fan headers coming off the AIO, and they don't work. Any ideas? 

 

Also, I have a 4 pin splitter I could plug into the motherboard fan header, but only one of them is 4 pin on the fan side. Why?

Check the fan curve settings in EVGA software, they may be set to a zero rpm mode if that's supported.

I played around with it a bit, plugged in the 3 pin instead and now the fans work. However they don't show up in the EVGA utilitys RPM section. At least they're working now though. I might just leave it, though I'd be curious as to why they don't register their speed.

Just be aware that on 3 pin headers you lose the PWM portion, I suspect as they are not connected to the AIO that is why they don't show up at present.

They are though, that's the odd part.

In reference to the splitter.

Assuming you mean like that above. Two fans into one splitter. One of the female ends has 4 pins but the other has 3 pins. 2 fans sending information back to the same motherboard header causes issues. The splitter uses the RPM signal of the 4 pin fan and assumes they're both the same speed. You'll get one speed signal from the header on the motherboard, but both fans will be at the same speed provided they're the same fans. 

As for why they won't work with the CLC, the manual is awfully bare and gives no real hints. Seems like people have complaints with the software as well.

Merci! 

I could have Googled it but it was a long day at work and I can't be arsed right now. Plus the 2080ti doesn't like the SF600. So I need to find a new PSU.

 

Odd that they weren't working when it first started up. If it were you, keep it connected to the AIO via 3 pin, or hook it up to the motherboard header via a splitter? Case only has the 2 radiator fans. 

 

There's a program that Jay was lushing over that monitored everything. I'll probably try and find that one.

Does the AIO only use 3 pin? If so, you need 3 pin DC fans. 4 pin connectors can do PWM or DC, but 4 pin(PWM) fans, need the 4th pin. They're wired differently too, but you can switch(at least on motherboards) from PWM to DC mode.

3 pin sends more or less voltage to control speed. 4 pin sends it in pulses using the PWM wire.

That's interesting. OCP? If so, I might rethink my SF600 a bit. A 2080TI *SHOULD* only be using about 10 more watts than my 6800 xt. 

 

Edit: Headed outside in a few. Almost on shift so I'll for sure be slow to reply.

It has 4 pin fan connections, but they terminate to a 3 pin for the CPU header IIRC. Kind of odd.

 

Yup. Wouldn't turn on at all for a bit, even the motherboard lighting stayed off. Is yours the Gold or Plat model? I have a feeling the Plat one would be a bit better. I'm not gonna mess around though, I'm going to see if I can source a 750w or 850w of something else. I was thinking it shouldn't be a problem either since it came from a system with a 600w PSU, and it's only 20w more than the 6700XT that presented no problems (other than semi frequent driver crashes).

That’s an odd one

Mine is gold. This will sound odd, but I was having the same issues with my SF600. What case do you have?
I thought I was hitting OCP, but after conversations with Johnny and some messing around with a temp gun, I was actually hitting OTP with my 5800x in an ITX case. I’m on mobile, but if you go to the link for Project Hot Box you can see towards the end of that where I was playing with temperatures and what not. 
For me changing my case fixed it. If you’re hitting OTP and not OCP better ventilation for the PSU will fix it. 
It shutting down and staying off sounds like temperature though. I would get shut down and about the time it took me to have a smoke I could fire back up like nothing happened.

I found your build log. I’m assuming the AIO is intake? The PSU will be getting hot air from the AIO. I was getting the same from my down draft air cooler. 
Try taking the side panel off. It looks like the AIO is mounted to that and could be set aside so the PSU gets fresh air. It looks like that comes off easy enough. 
See if it’ll crash like that.

The DA2. I don't think I'll be replacing it since getting something of similar quality would be....extremely expensive. Though the LianLi A4H20 is awfully tempting.

What's OTP? If the PSU itself gets too hot? The fan barely turns on even with Heaven, where the GPU sounds like it's trying to take off into the next room.

I was running it as exhaust with the 6700XT, intake with the 2080Ti. Right now it's intake with a 3060Ti.

That's a good point. The AIO does blow directly into the PSU, and the GPU blows up into the path of the AIO. Though, it was hard locking/blue screening on YT videos, so I'm not sure how much of a temperature issue that would have been. CPU was below 40 degrees. I haven't had the side panels on the case yet, as I was waiting to switch out the fans (massive improvement btw, I can't even tell the comp is on even with the fans in the upper levels of their range) and possibly the PSU to get rid of the coil whine.

 

Guess it might be worth switching it back to exhaust. Though I think I'm pretty set on just getting a beefier PSU.

Correct, however,

This doesn't sound like temperature. OTP will just shut the computer down. YouTube videos shouldn't be putting that much of a load. Out of curiosity, did you do DDU when swapping graphics cards?

(I know this got off topic of the fans, but it was sort of the natural progression of the thread)

Yeah, I took out all of the AMD stuff. I might run it again when I get the new PSU just to be on the safe side.

Haha, I don't mind if it's "off topic"; my thread, my rules

 

I'm hoping I manage to score an RTX 3070 over the next few days. Though I don't know if the slightly lower TDP would matter all that much.
