Fan issue

[r34gan]

Zotac Gtx 970 fan seems to be not functioning properly. No resistance when I spin it manually. Few years old so RMA is not on the table. Any fix. Probably will have to buy new ones.

Either buy direct replacements or ditch the shroud and install a couple 120mm or 92mm fans. A standard fan to VGA fan adapter can be had for cheap, as can a splitter.

Agree with @Demonic Donut. I did the same thing on my gfs gtx 1070. It works super well. I'll post a couple pictures later

I just swapped my other fan that was working properly into that slot and now it seems it is doing the same jittering spinning. Tried switching it back into its normal position and it’s keeping that habits. I don’t understand that much for electrical but why would it develop the jittery spin

I guessing that turning up the fan speed did nothing or made weird noises. If you spin it by hand is the any resistance?

I turned the fan to 100% in afterburner but it just spins for 1 seconds goes back and forth and then spins again going in this cycle. Never is fully spinning and there is no resistance. 
 

I’ve ended up upgrading to a rtx 2080s gigabyte. I know the new nvidia makes are coming sometime in September but replacement fans will take 20+ days to arrive. 
 

Think I might order the fans and build a PC for my dad. He’s always wanted to play a few games but the wife wouldn’t let him splash a load of cash on one

i ran into same the problem. Everything points to fans dying. Finding "new" replacements is highly unlikely. they will all be used and pulled from dead gpus.

 

honestly i would just zip tie 120mm or 92mm fans to the heatsink for the gpu. its much easier than it may seem. I did with the PCB attached to the heatsink as you can tell exactly where the zip ties can hold without interfering with anything. i you have to feed the tie through an area where it could rub any circuits be light-handed.   If you take this path. you'll have 3 options when controlling the fans.

 

• 1. case fan to vga connector (controls the fans the same way as before)
• 2. connect fans the motherboard (there are different ways to controls fan this way)
  • off set fan curve for the fans connected the gpu based on cpu temps
  • use FanControl as it can see gpu temps as set fans the way you want them
  • use a fan controller with manual controller
• use a fan hub like the Commander Pro which you can customize fan curves from multiple sensors such as gpu temp through ICUE( you can also connect RGB and control RGB( from corsair)  I think NZXT has something similar.

you could also use an aftermarket gpu/vga cooler that come with new fan and usually a better heatsink depending on your model. the 2 that i know of are:

arctic accelero

and

raijintek morpheus

these work really well. the downside is the cost. A used 970 run around 100$ ATM( would expect that to drop more very soon) these cooler run 70-100
