Have a 80mm fan. No arrows on it. Installed in front of case. I installed it with label facing on the inside of case (cant see label from outside). I know air flow goes from front to back. Is this fan installed right direction? Any way to visually tell?

I installed rear 120mm fan with label facing on outside (can see label from outside) - so it pushes air out of case. This fan had an arrow - so I faced the arrow pointing to outside of case.

Seems my temps are running hot. Not sure if fans are installed in correct directions.

you can tell which way the fan blade spins by which way the fins are pointing

 Spoiler:
 


Like this is going to spin counter clock wise. Theres no wrong way to install a fan, depends how you want it. Lets pretend your case is behind that fan. That fan spinning counter clockwise will be blowing air INTO your cace.



This one spins clockwise and will suck air out

Sound Advice, that's some scientific shit right there. Lab coats required. Smile

Thinking to put my Ninja in a push pull config...but I guess there is no space for it...I just got some new Arctic silver 5 as my temps are slowly getting sort a 45-50 (E6600@3.1Ghz) Idle. I suspect that one of those fracking pins on the 775 bracket have come loose (HATE THAT DESIGN!) + i got some new cable binders to really work on that cable management...but I think I will do this on the week end as it will take some hours etc.

i just love zalman for their devotion to low-noise cooling. Had a zalman-heatpipe on my gf4 and have a chipsetcooler on my abit nf7-s. Or to put it in an emo-metaphor: If zalman was a girl i wouldnt be able to talk to her, because i admire her too much Very Happy

Found problem.

Front fan was not spinning! Even though led lights worked - blades not moving. Also, installed back fan backwards. Air was flowing in.

Replaced front fan. Repositioned back fan so air pushes out. Huge drop in temperatures. Case overall averages 85 F.. CPU's average 75 F.. 3 HD's though seem to average around 95-100F.

Thanks for help!

85 Fahrenheit = 53 celcius
*subtract 32 to get celcius.

I dont know what celcius is over here. hahaha..

not so simple actually;)

85F = 29,4C

To convert Fahrenheit temperatures into Celsius:

* Begin by subtracting 32 from the Fahrenheit number.
* Divide the answer by 9.
* Then multiply that answer by 5.

BTW THAT TEMP IS REALLY LOW Wink

well, if he's got everything properly configured chances are his cpu will reduce it's multiplier to clock itself down, so that's most likely why the temperature is so low when idle. My good old athlon 64 was also around 30°C when idle thanks to Cool&Quiet eventhough it was overclocked big time.

HDDs get relatively hot, especially if they're close together. you should position them as far away from each other as possible.

what are you using to detect temp, cox? something that takes it from the motherboard, or coretemp, because theres a 10 degree c diff between the two...

I use CoreTemp
I guess its measuring very close to the core.
http://www.thecoolest.zerobrains.com/CoreTemp/

I also have TAT, but I never really use it as Core Temp seems to do the job.
I also tried hardware sensors monitor 4.3...with the same result, so I think the temps are showing correct.

I really think my prob is a combo of things.
I seated that heat sink maybe 10 months ago using Liquid Silver Pads (not paste) The case have never been really cleaned out (10 months), Bad cable management and I also suspect that the 775 fitting is not doing its job.

The fiddly bit is that I have to take out the hole mobo as the Ninja is so dam big, but I also need to really look over my cable management so I would have to do that anyway.

My Ninja's unsettled over time as well, damn thing gradually got hotter and hotter over the past 6 months. Yeah, Core-temp and TAT use a internal Diode to report temps not the bios' external shit that shows my CPU at like 20C.
