I got a Fractal Design Core 1000 micro-ATX casing which comes with one 120mm front intake fan. There are options for a 92mm rear exhaust fan and 120mm side panel fan. Here are my temperature readings using HWMonitor,
The motherboard is ASRock B75M-DGS and processor is Ivy Bridge Intel Core i5-3470, and graphics card is Radeon HD 6850 from HIS. Power supply is FSP Hexa 500, harddisk is Western Digital 1TB Caviar Blue. I took this snapshot when the PC was cool with no browser (for Min values) and then ran all my applications and a game Sims 3 (for Max values). Here are my concerns:
1. The graphics card was idling at 50-54 ºC. Is this too high for this card? I got it cheap second-hand. When running Sims 3, which isn't a heavy resource game, the temperature shot up to 73 ºC and I can hear the graphics card cooling fan spinning at full speed (3400 RPM blue fan). Do I need to install a 120mm side panel fan to the casing?
2. The CPU cores were idling at 38-42 ºC on room temperature of 28 ºC. When running at full loads, the temperatures ran up to 65 ºC and the Intel stock cooling fan spinning at 3100 RPM. Do I need to buy a 3rd party CPU cooler?
3. The Fractal Design Core 1000 casing's 120mm front intake fan is running at max 1200 RPM and quite noisy. I'm thinking of getting a 7V adapter cable to bring the fan speed down and reduce the noise. But then this will affect the intake air pressure too. Should I add a 92mm rear exhaust fan? The top mounted FSP Hexa 500 power supply already has a 120mm exhaust fan, although it appears to suck in air from the CPU fan cooler into the power supply electronics.
4. Should I install the 120mm side panel fan blowing into the graphics card, or blowing out to extract the hot air? The pre-installed front intake 120mm fan is 40.6 CFM so does it matter what kind of airflow spec to choose for the side panel and rear fans?
The thing is, if I add two more case fans (rear 92mm and side panel 120mm) it would make the PC even noisier right? When I ran the system at full loads, I can hear the Intel stock cooling fan's 3100 RPM and the HD 6850 cooling fan's 3400 RPM and they are even noisier than the 120mm casing fan. What can I do to balance the need for low noise and low temperature? If I add the two fans and then step down the voltage from 12V to 7V to reduce the RPM and noise, it would defeat the purpose of adding the fans right?
