Thermaltake Riing fans - Lack of PWM

I bought some Thermaltake Riing 120mm fans to swap out the standard fans on my Corsair H100i GTX.

They look lovely, but I've only noticed after fitting them that the fans don't have PWM, so are running at 100% all of the time, so loud!!

Is there any cheap/easy way to make the fans PWM? They both plug directly into the AIO's CPU block.

Can you plug them into a motherboard header and adjust the voltage to the header?
 
I'd assume Ste means the four pin plug that goes from pump to cpu fan header on motherboard, you should still be able to control fan speeds in corsair link but the software can be buggy sometimes . I've just done a fresh install and now my fans , water temp and pump speed don't show in the link panel . I'd reinstall corsair link first

I'll reinstall the software, see if it helps. But I fear the fact they're not PWM fans is the root cause.

I'd return them and get some pwm fans, personally.

Popular auction site purchase, nsoxnot possible. Plus, I need fans with a white halo LED effect.
 
The H100i is not designed for voltage controlled fans. Even if it was, Corsair have a history of not recognising voltage fans and driving them flat out...which oddly is what you are seeing!! You have a few ways of getting round this. Firstly, return the fans and get PWM! Honestly that is the best solution. Secondly, you could connect the fans to your motherboard CPU fan via the Corsair splitter. Your motherboard should recognise them as voltage fans and control them appropriately. The third option is to just buy a simply fan controller from ebay ( switched perhaps ) and just have the fans at a static speed all the time. Say about 1000RPM. Sounds stupid, but really it would be just fine.
 
If the Corsair thing has a 4 pin connector that could be used as a PWM source for a PWM hub. It would be a bit of a hack to get it working but that's what I'd do.

Bear in mind though that unless you drive the fans at an appreciable voltage you'll lose brightness on the LEDs. That's why in these cases PWM is better as they always get the full 12v, no matter what the fan speed.

Would this work?

Might work. It is a PWM controlled adapter hub for variable speed fans. Potential problem is it's voltage range varies with total fan amp load. At low amp load it does not lower the voltage as much so fans will not idle down to low rpm many of us want them at when load/heat is low. For example if 2x fans draw 0.3 amp and hub is receiving 20% PWM signal the hub's headers will be supplying about 7.7 volts to the 2 fans.
