Hey all, i just installed my new Case, CPU cooler and PSU in preperation for my new 2 baby's (HD5870's) 

I was internetting yesterday for 2 hours and havn't played any games so far, on IDLE temps the CPU (Core i7 920 @ stock 2.66ghz) is around 15-18 degrees  the CPU Cooler is a V10 Cooler Master and Artic Silver 5 paste, the Case is an Antec 1200 and the PSU a Corsair HX850

while getting these temperatures all case fans are set to low, but once a 30 minutes something blows REALLY hard for 5-10 seconds, i dont know if it's either the V10 or the Case Fans, but the CPU is at a steady 15-18 degrees (all cores) 

anyone knows if 15-18 degrees is to cold or just fine? because with my stock cooler i had idle temperatures for 65 degrees

and what could the massive airblow be which is done once in a while for 5-10 secs while all temperatures are really low including the area temperatures

yes... show us how badass rig you have.

if you put that rig together you should know those temps are perfect.

BTW check your bios and MOBO manual where did you plugged the fans.

open the case and try to notice which fan is speeding up.use your finger to stop the fan when it becomes loud (just for a sec).

usually the CPU coolers speed up.

if your ambient temp is more than 15-18 degrees .then i think it doesnt detect the temps correctly .

are you using any application to check?because speedfan can detect it wrong

best to check it in bios.

Those temps aren't real. Use realtemp or other similar program to get more convincing results. 

I think these temps are real though, because it detects not all around that temperature, V10 is known for cooling below ambient temperatures

And the program i use actually matches with my ATI's CCC, it says nearly the exact same temperature as the GPU (40-44 degrees) but when iam home i'll look into the BIOS what the true temperatures are, and i will try different software.

when i put my casefans on high after 10-15 minutes all the system temperature is below 40 degrees, including GPU, i have cable managed all the cables really well and the Airflow is just great, the Antec 1200 case is great!

when i put my case fans on HIGH the CPU has the following temperatures: 

Core0 17

Core1 16

Core2 16

Core3 15

and on LOW about  19,17,18,18

And Also on the comment: With that rig you should know if that's good

Well to be honest, this is my first NON-stock cooler ever, i've always used stock cooling.

Unless you live in an iglu, you are breaking physic laws. Those temps are quite far from real temps.

lol you don't want sub-ambient temps.  It means your case is producing electronic destroying condensation.  However, its pretty impossible to get sub ambient temps using air cooling.

I don't think the v10 comes with bios controlled cooling, so I don't think the fan speed increase is coming from that.  Are your case fans controlled by the controller or mobo?  If so it could be a bios thing that has them go up for a few seconds.  Either that or an over voltage from the PSU.

I actually think this is how the V10 works, i just read this review and the review has the exact same thing as me, look here:

 "Ambient Temp. 75F (24C)

Core0

Under Load: 24C

Idle: 17C

Core1

Under Load: 14C

Idle: 7C

Measurements with my hand held IR thermometers concur. 6 degrees lower than the stock cooler. More impressive, the V10's Peltier Element can cool a CPU to below the ambient temperature. Wait what am I saying here? A stock CPU cooler uses the ambient air to cool the CPU. It other words it just moves the air, it can't lower the temperature below that of the air in the room. The V10 with TEC actually lowers the temperature.

At the moment I am testing water cooling systems for a future article. The V10 CPU cooler out performs all of them. A water cooling system attempts to lower the temperature by running water over a CPU block. Then it runs the water through a radiator which lowers the temperature. I was amazed when I saw the results. I did additional tests which all turn out the same averages.

The fans are rpm controlled. But even at full load the fans where barely noticeable. Of course this might also be because of the excellent isolation of the Cosmos case."

However i use an Antec 1200 with 6 ventilators in it, i actually have higher temperatures, but as you can see his temperature is even more below ambient temperatures!  even while load!

he was using an Intel® Pentium® Dual-Core T2370 1.73ghz processor though. but as you can see, it cools below ambient temperatures, so was his stock cooler, so i think it has to do with the Antec 1200 and the Cosmos cases, and other quality cases with LOADS of ventilation.
 

Sweet jesus, just look around a little bit. Take a look at physics book, you can't go lower than ambient temperature, it's simply not possible.

Ahh well okay, i'll just overclock the heck out of the i7 to about 3.8-4.0ghz and see how it goes ;) 

thanks for all the responses :) will look into the 'Blowouts' and see if i can fix it, they are not applied to a motherboard controller, i can manually set the speed of the fans with buttons applied to the case

so those massive blowouts can be caused by the PSU getting too much voltage? if so, how can i fix that?

Try the realtemp software, I'm curious to see.

Will post them in this topic and PM you in 4 hours, iam at work now so can't do it,  btw my apology for being so selfish to believe that my temperatures are below ambient room, i hope that the realtemp software will show accurate numbers.

Wow I didn't realize the V10 had a Peltier cooler on it as well. You actually can go below ambient temperature using that - they are right if this was just an air cooler it would be impossible, but the Peltier (TEC) cooler basically makes one side of the heatsink a fridge and the other a radiator, allowing you to get the CPU below ambient with good cooling.

From what I briefly read about the V10 though it's suppose to be a hybrid Peltier cooler that only kicks in at hot temperatures, but it sounds like it's always on if your idle is below ambient. Only problem with this is the Peltier cooler takes quite a bit of power to run and you don't really need to idle below ambient temperature.

It's a very low power one, generally able to lower temps only by 2-4 degrees according to reviews.

Ah.. yea that sounds much more likely, $130 for a giant heatsink like that WITH a quality Peltier cooler would be too good.

You guys were totally right, i have SpeedFan and Real Temp on now, Speedfan says 18 degrees, and Real Temp says 31 degrees average

I've just ran Prime95 and it's 50 degrees on 100% load, but the thing is... my Cooler Master V10 fans are not going faster when the temperature increases...

A fans speed is controlled by the voltage sent to the fan.  If the fan is connected directly to the PSU then its most likely spikes in voltage which would be a bad thing.  However, yours are controlled by a fan controller.  The possibility here is that the fan controller does a reset every few hours, when it does it no longer controls the voltage and sends the full power to the fans causing them to 100%.

How many rpm's does it say your fan is spinning at when idle vs load?

Yep realtemps is a good program for accuracy over speedfan.

V10 is not it is all it is made out to be. Your not going to have any issues with your PSU either :)

The fan is at 1000RPM when idle, and 1400-1500 when on Load,

but now that i've been looking in the BIOS.. the BIOS displays the same temperatures as Speedfan which is 18 degrees Idle, btw, my ambient temp's are around 19-20 degrees.

so maybe the BIOS and Speedfan is correct afterall?

Its rumored that Intel uses a poor method for measuring temperature.  Its possible in this case.  There is currently only 1 type of cooling method that produces sub-ambient temperatures, and thats using a compressar that costs $900.

No, they are not correct.
 

Yes, Intel measures their CPU temps by 'degrees below overheating'. So if a CPU is rated for max of say 75C before blowing up, and it's running at 50C, then what the sensor actually reports is -25C. Problem is they changed the specs on some of their CPU's to be rated for say 95C but the mobo BIOS's were still under the assumption (either the CPU was telling it or the BIOS has it predetermined) that the CPU's max temp was 75C. So the CPU reports -45C (45 below 95), and the mobo is still thinking this is 45 below 75 so puts it at 30C.

So I wouldn't be surprised if realtemp compensates for this but a BIOS update might correct the temp reporting. I don't remember the specifics, if it was a BIOS problem or a CPU problem.. I actually have a feeling the CPU tells the mobo what its max temp is so if that's the case a BIOS update may not fix it.
