| 313400 | 2005-01-13 08:03:00 | reading from JJJJJ's first post he only has 1 fan, that is the cpu, and a hole at the back so he doesnt really have air flow, why dont you try, 80mm fans are dirt cheap these days | Prescott (11) | ||

| 313405 | 2005-01-13 21:23:00 | To increase the airflow you should install a 120mm fan in the front of your case, most cases have a pre-cut hole for the fan. Just check to see that you case actually allows air to be sucked in from the front. My case had the hole for the fan but the plastic casing covering the actual metal chassis didn't, so I ended up drilling holes into the plastic casing to allow the air through. MY CPU is overclocked by 600Mhz and before I had the fan in the front, the CPU temp was usually around 47-49 degrees, the motherboard temperature was round about 44- 46 degrees. Now I usually average 39-42 degrees for the CPU and 37-39 for the mobo. It gets up to 47-49 when I'm playing Doom3 or HL2 but it doesn't take long for the temp to go back down again. I also have another fan at the rear of my case which extracts air. The basic rule is to make sure that air is drawn into the case and then extracted out of it again. Essentially you want an airflow direction of FRONT TO BACK. Hope that helps cheers chiefnz |

Did you actually have any heat related problems before adding the extra fan? Or was it a peace of mind thing? Temp readings aren't very accurate . Some motherboard manufacturers have altered their bioses to reduce apparently high reported temps when there weren't any actual problems occurring . Real temps below 60 on load shouldn't be a problem . |

| 313408 | 2005-01-13 23:11:00 | Susan, as long as you don't use refrigeration (such as a Peltier element) the case of the CPU can never get cooler than the air around it . Ever . The CPU chip can't get cooler than the package it's in . Ever . Hotter, yes . This can be a problem . It's to do with the second law of thermodynamics . That's been the dowbnfall of many "clever" ideas . AIDA or any other programme whuch reports temperatures is only a programme . IT only knows what it has been told . It makes a calculation based on the number it gets from the sensor . Sensors are cheap . To be cheap they are not make to close tolerances . You have to calibrate them before you can trust the measurements . I have been playing with a very clever little temperature sensor . It gives 12 bit output, with resolution to 1/16 of a degree . Without special adjustments it's accurate to 1/2 degree . A wonderful little device . It can give alarms when it sees temperatures above or below limits you set . But the manufacturers had a problem with batch B7 . These units can randomly change their calibration numbers when they are powered up . After that, they can be wrong by up to 20 degrees . So to use them, you have to be very careful . You read the calibration constants the first time you use them . Then, each time, youi have to load the saved values into the unit . You can't trust measurements . When a device which is using 30 or 40 watts of power is said to be even 4 degrees cooler than the air around it, the measurement is WRONG . |

No I didn't have any problems, but after all the research I did on how far my CPU could be over-clocked, I thought it best to add the extra fans. cheers chiefnz |
