Why is my CPU FAN always at 100%?

Why is TMPIN1 so high?

System Specification
- Case: Coolermaster CM 690 II Advanced
- Power Supply: OCZ ZS 650w PSU
- CPU: Intel Core i5 2500K 3.30GHz Overclocked to 4.60GHz
- Motherboard: MSI Z68A-G45
- Cooler: OcUK H2Flow CPU cooler
- RAM: 8GB DDR3 1600MHz Dual Channel Kit
- Hard Drive: 1TB + OCZ 60GB Sata 6GB/s Solid State Drive
- Graphics Card: OCUK Nvidia GTX 580
- Optical Drive: DVD+/-RW SATA Drive

Should i buy a couple of case fans?

If so..which ones and how many?
How do I connect them?
To the motherboard or the PSU? (My mobo manual says I have 4 SYSFAN sockets available.)
Where do you suggest I position them? Top, bottom or side?


Thank you for your help!

Put one of these on the PWM fan head (one located near the CPU)

Get these PWM fans while they're on TWO:

Connect them to the cable splitter. As they're PWM, they will be controlled via the motherboard, so will only speed up if PC gets hot.

or if you have a budget, let me know and we can adjust the fans :)

Bottom = Intake, Side = Intake, Top = exhaust, Rear = Exhaust
 
I had the original CM 690 and that is how I had the fans positioned in mine ^ ^ :)

Fan-wise I had a couple of Yate Loons and a Silent Eagle iirc. Really liked that case, so when I upgraded I now use it in my office.

What is the PWM fan head? And why do I need that cable? Could I just not plug them into their own seperate sockets on the motherboard? Or am I missing something?

How many would you suggest I buy? There is space for two fans on the left side of the case, two at the top, and 1 at the bottom I think. Am I right in thinking that 2 intake fans on the left and 2 exhaust fans on the top will get good airflow going?

What sizes?

Thank you for your help.

It basically means the fans wont run at 100% all the time(more friendly on the ears) and will vary depending on the temp of the CPU.

The fans I linked are all PWM fans, a lot of boards only come with 1xPWM header and the rest are 3-pin headers, hence the extension cable to make the PWM header run 5 PWM fans.

As long as you get a decent airflow in the case, it doesn't matter how many, as you dont need to kill all the slots (although I have on my CM690 II :))

Oh and size should be 120mm.

The other route is pick up normal 3-pin fans and then get a fan controller to manually control the speed yourself.

My cpu cooler(3 pin) plugs into my CPUFAN socket shown in the pic below.

If I was to get the 5 PWM cable adapter, i would plug that into the CPUFAN socket instead, and then plug my CPU cooler into the adapter, aswell as my new case fans...is that right?

Will the cable adapter still detect the CPU fan even though the cpu cooler uses 3 pins? and the adapter has 4 pin sockets?

Thats correct; The splitter would go in to the CPU Fan header.

I said 120mm as that will fit in all the Fan slots, where as 140mm will only fit in a few:

http://www.overclockers.co.uk/showproduct.php?prodid=CA-196-CM&groupid=701&catid=7&subcat=29

- Front Cooling: 1 x 140mm Blue LED Fan
- Rear Cooling: 1 x 120mm Fan
- Top Cooling: 1 x 140mm Fan
- Bottom Cooling: 2 x 120mm Fans (optional)
- Right Side Cooling: 2 x 120 or 140mm Fans (optional)
- Left Side Cooling: 1 x 80mm Fan
- HDD Cage Cooling: 1 x 120mm Fan (optional)
- VGA Holder: 1 x 80mm Fan (optional)

You're more than happy to mix 140mm with the 120mm, just make sure you get it for the right side :)
 
Do you think the reason I have such a high mobo temperature is due to the lack of fan at the top?

The description you posted of my case seems to imply that I should have another fan as standard at the top.

Well depending on budget, just get the fans you need. :) I've got my CM690 II filled and temps idle at <30c with I5 2500K @ 4.5ghz. I will see what they get to while playing BF3, but it should be less than 40c hopefully.
 
I have my CM690 II filled with Fractal Fans.

1 x 140mm at the front
2 x 140mm at the top
1 x 120mm at the back
Noctua fan on my CPU Cooler

Runs nice and cold and quiet. :)

PapaLazaru, do you mind taking a couple of photos?

Why did you chose not to put any fans on the side?

Hi. I will take some if I remember, but I am not at home at the moment (gf's laptop).

The Fractal fans always get good reviews and they are very quiet. I like the white colour as well. I did not stick some on the side as I have always found them to get in the way when I want to have a poke about inside. My temps are good as they are as well. I have DEMCiflex Dust Filters on both the side holes and the one on the other side behind the CPU (where you can put yet another fan if you want).

What I have considered, and what you may also wish to consider, is puttting an 80mmm fan on the GPU bracket. I am not sure how it works but there is a part that attaches to the side of the gpu to help hold it rigid and it has a couple of screw holes for a fan, which aims right at the GPU.

The review below swayed me to those fans but I have had to cover a bit up as it is from a competitor website. :)

Thanks for the reply.

I've figured out that the high TMPIN1 temperature is the southbridge/PCH on the motherboard. The heatsink for the southbridge is almost completely covered by the gtx580 meaning hot air is being blown on to it, causing the high temps. I have a spare pci-e slot that the 580 can fit which won't cover the PCH/Southbridge heatsink.

Will I have any problems if I use this slot for the GTX580 instead?
 
Just tried to install the card into the second PCI-E slot but it was blocked by a bunch of SATA cables. Really disappointed with this motherboard. You would think they would position these things correctly.

I guess my last option is to get a side intake fan over the GPU/Chipset area to hopefully cool it down a bit. And an exhaust fan at the top.
 
Can you not bend the Sata cables to get it in? Well not enough to break them that is :D

Nope, unfortunately not. It's not the cable that is in the way, but the plug of the cable. The cable is as out of the way as possible.

Right, I'm gonna go for some 140mm fans...I'm not sure if I should get the 4 pin Akasa : http://www.overclockers.co.uk/showproduct.php?prodid=FG-063-AK and have it vary speed according to CPU or get 3 pin fans and plug directly into the motherboard, and use software to control the speeds.

I don't really need them to vary according to the CPU....do i? Because the southbridge temperature problem is not caused by the CPU.

What do you guys think?
