Rig cooling at 74-78 Celcius for past 12hrs good? - Page 2

post #11 of 18
80c for extended load like are doing is at the top of safe range..
I keep mine below 70c
In fact at 3.5GHz on prime @100% CPU it peaks at 61c. Ambient 22c.
I just haven't OC'ed more after changing HSF from NH-U12P to Phanteks PH-TC14PE
On NH-U12P max was 70c.

so 79c with 34c ambient is not bad

Thanks, and looking over your pc specs, How did you wire the fans all to the cpu fan? Wouldn't that be to much of a power draw or? (Wasn't sure if pure power, or whichever).

And how are you getting 3.55 (same proc as mine), ie, what clock/multi? As i'd like to increase speed/drop temps, but stay stable if possible.

you can order a PWM splitter that draws power directly from the PSU but the speed is still controlled by the mobo header. pwm header has 4 wires which are ground, 12v, tach, and PWM signal. the ground, power, tach wires are pretty much exactly like the regular 3 pin except PWM fans do no modulate the voltage of the power to change the speed of the fan. instead it uses the PWM signal to control the speed. so the splitter would simply supply full 12v power to the fan while the logic board on the back of the fan actually control the speed of the fan using the PWM signal from your mobo header.

I will have to remember that when I make my next case build in a year or 2. Hopefully I can get a super tower, and really seriously wire it properly this time. That's an awesome part i'd toss in for sure!

As psyclum said, PWM splitters using molex socket powered by PSU.

Akasa and Gelid sell them.

One CPU cooler fan is master rpm signal to motherboard PMW CPU fan socket. I have 2 PWM splitters giving me 9 sockets so could put in 2 more fans. biggrin.gif

You need to use fans of similar rpm range so they all runs similar speeds. I'm using 4x TY-140 and 3x FN053 fans.

So basically, the long story short, get same type fans if possible for all positions, and voila, perfection? smile.gif

not quite. fans are selected for their function and location. generally speaking you want fans with higher static pressure for intake fans since you should have filters on all your intake fans. all other fans do not need filters since the intake fan has already taken care of the filtration of incoming air. you want to try to match the CFM of intake with exhaust, however the filter cuts down on the intake CFM by as much as 50% so you should take that into consideration when making your CFM calculations of intake / exhaust fan placement. other mistakes people make when designing airflow solution for their computer is they neglect to account for PSU and GPU exhaust as part of the exhaust CFM calculation. so long story short, you generally want more intake fans then exhaust. in fact if the case is designed properly with exhaust points in the correct places, you don't actually need any exhaust fans at all. hot air will naturally flow out of the case at those exhaust ports if you have positive case pressure.

You just translated alot of math concepts, into english lamen. You sir are awesome. smile.gif Thanks for the info!
