First off, i'd just like to say i love this P182. It's the ducks guts! I've owned an series 1 Antec Nine Hundred for about a year now and it's served me very well. I only air cool, so i bought it with some high performance, overclocked, air cooled hardware in mind. I'm since over that and want a nice clean case without 6 jigawatts of LED's luminating my room and a bit of peace and quiet from the howling monster would be nice But let me say, i still love the Nine Hundred and it's howling jigawatts... just need a break from it. So i bought myself a new P182! Now the big question is, how much better is the 900 at cooling, compared to the P182? Before i get onto the results i'll just share some specs... Antec Nine Hundred: 1x 200mm fan (low) above CPU 1x120mm fan (low) behind CPU 2x120mm fan (low) infront of HDD's Antec P182: 1x120mm fan (low) above CPU 1x120mm fan (low) behind CPU 1x120mm fan (low) front, middle of case A quick shot from the install to get an idea on how it's laid out: Yeah, new board! EP35-DS3P... fkn love it So the HDD's down below, and the PSU have no fan dedicated to them, yet, and you'll see why i say "yet". Both cases are completely assembled with side panels intact and ambient temperature remained the same. Idle Temp So, how do we go with idle temps? Antec 900 GPU: 45c CPU: 37/36/35/39c HDD: 33c Antec P182 GPU: 45c CPU: 38/36/37/40c HDD: 42c Not too bad! As you can see, the HDD is roasting compared to before, but it's well within it's operational temperature... and no, they don't get any hotter, i tried making it get hotter GPU Temps Hokay, so what about the GPU loaded? Want to know what difference we're up against when gaming! Antec 900 5 minutes in Uniengine GPU Load: 61c Antec P182 5 minutes in Uniengine GPU Load: 63c CPU Loaded Lastly, we need to ask what the CPU thinks about this new home. I ran Prime95 with the Tuniq fan on it's lowest setting for the first 2 tests then recorded the temp. As soon as the 3rd test was underway, i upped the Tuniq's fan to 100%. Once the 5th test had started i took the temp readings again. So, idle fan for 2 tests, and full fan for next 2 tests. Antec 900 CPU Load - Low Fan: 63/62/62/62 CPU Load - High Fan: 59/58/58/58 Antec P182 CPU Load - Low Fan: 63/62/62/62 CPU Load - High Fan: 58/57/57/57 Well whattya know! The CPU load temps are pretty bang on identical! Well it's been fun, but time 4 sleeps! Cheers!
