Hello all, Im wondering if the fan header located near the tubing can support 2 noctua af-12s on a splitter? I have been running them after reading another post in regards that said it would support 1amp. The fans draw .14 according to Noctua. The reason im asking is i often notice my temp going from its normal 50c underload into the mid 60s. To rectify this i have to click default in the x1 software. Im basically just wondering if this is a common issue or something coming up do to the power draw of the fans. Thanks.

The fan header will work with the curve you put in PX1 thus putting a tad bit more power draw/load on the card which could explain the temps. How do you have the radiator mounted? Does this happen without the fans connected? I know you said if you hit default, is the card overclocked?

I runned 2 noctua IPPC fans and there was no issue with power.
What is your problem actually? That your GPU wokring under 65C (that is completly normal for low speed fans - for example, I have under 70c in games while fans going up to 1300rpm, while with 2000rpm gpu maximum temperature is 57C in furmark) or what? What do you mean "by clicking default in x1" - what setting are you using?

There is bug with x1 and maybe TS facing it: everytime x1 updates fans settings - rad fans actuallly turns off and startup again from 0RPM to needed. For example, if you change from 90% to 80% or from 80% to 90% - fan just stops and it takes about 30 seconds to reach 80% or 90% again. So when fan curve is used - fan stops everysecond and average rpm is low - but in that case gpu will overheat like it was in this topic: https://forums.evga.com/2080TI-FTW3-ULTRA-HYBRID-core-clock-drop-m3005702.aspx

That is an incredibly strange bug. I assume our PM team is aware of it. Is that only happening in 1.02? What about previous versions?

Can't say - right now I am controlling both pump and fan speeds via motherboard, so this header is not connected to videocard anymore. Maybe this issue is related to hybrid cards only.

Im running the default settings on the card. I watched and the pull fan had stopped spinning entirely, the push fan was "pulsing" it would spin up then stop and then spin up and then stop. Clicking default totally rectified the issue, but it does this almost everytime i bring my computer out of sleep. I was thinking it was an issue with the fan connector coming out of the card. But it doesn't make sense if clicking default totally solves the problem.
To answer the questions above it is at the default setting.
The radiator is mounted as an exhaust with push/pull.
The problem is my gpu runs a 50-51c during all day gaming sessions. Almost everytime i first log on (bring my pc out of sleep) I'll start playing and will watch my radiator fans spin sporadically / not spin at all, and the temp will rise to 65c+ within 10 minutes until clicking default. After doing so the fans will spin and the temps will drop to that 50-51c within a few minutes.

It means that there is fan curve controlled via x1 and you facing described bug. But everytime you press "default" - x1 revert all its settings and setting fan to auto, so bios controls it. You should check if manual fan curve enabled in x1 and disable it: fans must be on auto with bios controlled curve, x1 should launched with bios controlled fan or it should not apply any settings on application launch. Or you can use msi afterburner instead of x1 if you need overclock only: it even can't control rad fans at all, only vrm fan is able to be controlled via afterburner ;) BTW it is better to have same (similar) fans for push-pull configuration. If one of your fans stops and never turns on while other fan is trying to run somehow - that mean you have two different fans on your radiator.

I have 2 Noctua Af-12s on the radiator they are for sure the same fans. The manual fan curve is disabled. I haven’t changed any settings from the default load out.

You didn't, but maybe there was some settings enabled by default after install. Your fans behave like there is fan curve enabled in x1.
Does any problem occurs if you just don't launch x1 and disable its autostart?

I will restart and see what happens when it’s not running at all.

So I am now running my fans attached to the mb header. Running 2 Noctua nf12s at 70% my gpu is running at 53c during loops of timespy. Seems to be working much better. It’s just unfortunate that I can’t use the x1 software to control ramping and what not.
