Cpu air cooler

Have you enabled cpu q fan control in bios? The k2 fans are rated as follows,

140mm, 1100 rpm
120mm, 1500 rpm.

Under monitoring in bios, enable cpu fan control and select one of the profiles, silent, standard and turbo iirc. Save theese settings and boot into windows. Also, what connectors have you connected the fans too on the motherboard? The fans should ramp upto full speed under cpu load.
 
Are the fans ramping up under cpu load at all? Ie stress testing such as prime95. I have the same cooler myself, but when i used the stock fans they were attached to separate 4 pin cpu fan headers.
 
I will try that, yea you get the 4 pin adapters but I used the daisy chain type connector to connect them both together then into the 1 cpu slot
 
yea just checked prime95 and the fans ramped up no problem, just don't know why its idle is so high I know its hot but im getting an idle of around 45c on all cores
 
Yep, never bothered with that myself mate as on the previous x58 board i used a PWM splitter cable from akasa. New board in sig has dual cpu fan headers.
 
ok mate ill re apply some , what kind of idle temps you think I should be getting bearing in mind its very very hot in my room lol
 
At a very rough estimate mate, taking into account your room temp, case airflow etc id be looking at mid 30's at idle. For comparison, my 3770k in a room thats at a rather toasty 26c, my idles are. 33-32-25-34. I disregard the 25c one though as it may be a stuck sensor, as theirs no way its running lower than ambient room temp. Same cooler but the fans are x2 120mm akasa piranhas currently running at 700 rpm.
 
What is your room temperature?
What is the temperature of air going into cooler? Easy way to check your case temperature is a cheapo indoor/outdoor wired remote digital thermometer. Refrigerator or terrarium thermometer of same basic design work good too. Can be had for £3-4 on auction site. Twist a piece of insulated wire into the last 6" or so and mount it in front of cooler about 1-2" and set the readout where it's easy for you to keep an eye on to see what the air temp going into cooler is at idle and load. They shouldn't be more than a couple degrees warmer.. 5c at most than the room. Every degree warmer is a degree warmer the CPU will be.
 
Don't look at the absolute temps, but the relative temps. How warm it is over ambient, that's a better metric, especially in this hot climate, and if you case has poor ventilation (although the Zalman should be packed with fans), the can affect the efficiency.
 
So cooler intake air is 18c warmer now than in winter.
45c - 35c = 10c.
If cooler intake was 21-23c your CPU would be 31-33c.. which is not bad.

took the pc out my room downstairs and its idle now is 40c still abit high though im going to re do the thermal paste and check again
 
re did the thermal paste but no change to the temps must just have a really hot house spent £60 to have the same temps hmm
