50'c with Tuniq Tower & DS4 [advice please]

Hey, I'm off to my mates in 15mins - he's getting 50'c with his Tuniq Tower. He's got idle temps of 23'c, and after taking the workload off the processor it takes like a second to return down to 23'c.

So based on that, I rekon the cooler's attached fine but it's just the fan isn't kicking in enough under load.

He's using a Gigabyte DS4 motherboard. Can anyone tell me what to disable/enable/etc to get his CPU fan working best?

Also, with the Tuniq Tower, you have the fan controller cable (2 pin) and the fan cable itself (3 pin) for the mobo. He has only got the fan cable for the mobo (3 pin) plugged in - the Tuniq's controller cable (2 pin) isn't plugged into anything... is that OK or does it need to be plugged in?

You dont have to plug the controller into the 2 pin if you dont wish it just means you can slow the fan down manually if its too noisey. If you do not plug it in it will run at full pelt anyhow. Also what cpu vcore is he running in the bios as this will have a massive effect on temps, you basically want the lowest stable vcore for whatever cpu speed he's running....is he doing a massive overclock? What thermal paste is he using, Artic Silver 5 is the one of choice. Also is he using too much/too little paste as again this will have an effect on temps. There are loads of theories on how to apply te paste but in my experience a very thin evenly spread (using credit card or something) works best.

Yeah he's using a thin layer of AS5, no overclock, and stock volts which I believe are around 1.3v on a DS4 (when I had one it was around there).

I think it's the thermal management that needs playing with on the mobo..?

Try using something like speedfan to monitor the cpu fan speeds under load.
I think the DS4 has a bios function called C1E which when set to enable reduces the vcore when not under load. This would explain the rapid decrease in heat when load conditions are stopped. Try using CPUz to monitor the vcore settings at idle and load.
