H80i Fan control not using link?

SM125 · Sep 22, 2014

Recently fit my H80i and it was a pain in the arse to install, after doing so i realised i couldnt get the link usb in due to large hands and small case (I know, i'm an idiot).

The cooler is running fine at the moment, apart from quite a loud clicking noise every now and then which im assuming is the pump.

My question is, is there a program (other than using smart fan control or corsair link) to quieten down the fans?

My friend also has the H80i on the rear 120mm mount as an intake and his is running at really low temps like 24c idle on the SILENT mode!? Mine is running at 2400rpm and at 31c idle as an exhaust, so im not sure if im doing something wrong also.

Thanks in advance and sorry for any bad english, im tired!

For connecting the USB you can use an external cable, it does not have to connect straight to the motherboard. A usb cable like that costs around 3-10$.

The clicking noise can come for a faulty fan bearing - happened to my H100i fan, better RMA it for a new one since that noise is maddening.

You can use an external fan controller or just connect the fans to your motherboard and control them through the BIOS itself of an application such as Speedfan.

The temperature difference can have a lot of explanations ill try to name a few:
1) Different thermal compounds can yield different results.
2) Improper mounting of the cooler can cause a few degrees overheat.
3) better case air intake can make sure that the air exhausted by your H80i is cooler and cools the radiator down further.
4) Radiators can only cool as low as your ambient room temperature, colder room means colder components - is your friend playing with an AC on?

If you have any more questions feel free to contact me.

Thanks for the in depth response!

Was hoping I wouldn't need to send it back, once I start something somewhat intensive and the fan speed increases, the noise goes, which is what's confusing me, it could be something as silly as a wire catching on a blade I suppose.

As for my friends temps, his room was roughly the same temperature, no windows open or any AC, although he does have a few extra case fans.

Actually thinking about it, my processor is an APU, maybe because it's having to deal with both a CPU and GPU's job on the same die could be why mines running hotter?

A chip that deals with more work is likely to be hotter yes

if its indeed the same chip you are comparing, each chip has its own thermal profile and even the same chips can act differently.

What you are describing can easily be something getting in the way of the fan, if the noise goes down at high RPM it seems like a bad bearing. At a lot speed the bearing as room to wiggle and make noise, once it gets higher the rotation can balance it hence the less noise (from the wiggling of-course).

I believe in sending faulty items back, if you payed for something it should be working right and without compromise! And trust me i know the down time for not having your system complete can be annoying, but in the long run you will enjoy your system more once its complete.

Not sure if this helps, but when I tip my PC towards it's side, so that the motherboard is closer to the ground, the knocking goes. Pump?

Can be, when the pump makes a slight grinding sound that can be an indication of an air bubble trapped in the system.

If you can disconnect the whole loop and give it a good shake it might get things moving.
