Ok let’s start out by explaining my system:
Ok now that is out of the way I will explain what I tested! There are a lot of people out there that tell you to leave your case open or to not even put your components in a case at all! Well I wanted to test this theory!
Room temperature 72.6F
I turned my CPU fan down to it's lowest setting ~ 1100rpm took the side case door off and let the case set for an hour while crunching SETI (100% CPU). I then replaced the side door to see the effect.
Here are the measurements:
OPEN -- Case Temp = 34C
Closed - Case Temp = 28C
OPEN -- HD Temp = 41C
Closed - HD Temp = 37C
OPEN -- CPU Temp = 53C
Closed - CPU Temp = 56C
And here is another graph when I Open the case back up (This one also has the CPU Temp):
So I guess this shows that your CPU runs cooler with an open case but because of the lack of moving airflow over the board components the MB and components heat up??? Does anyone else come to this conclusion?
Just for grins, this is the results on a closed case when I turn my Volcano 12 from 1100rpm (Stats say it only goes down to 2000 but mine goes down to 1100?) to its normal operating of 3800 to where the db is tolerable! Full 5500 rpm is enough to blow your eardrums out!
From 55C to 46C not to bad cooling while at 100% CPU!
The Stock Heatsync and Fan were running around 56 degrees while the CPU was at 100%, that was just toooo hot for me. I like to stay below 50!
This is my first Benchmark type post so please be easy on me but I do very much appreciate constructive criticism! I do not know that much about Overclocking but I do know a lot about testing and statistics! So I will contribute where I can!
