| 311191 | 2005-01-06 07:22:00 | Seeing as it was such a hot day I kept a close eye on my cpu temps while running bionic(seti). Normally I would run at 53-55 degrees on a mid-20 degree day but today after about half an hour it was already pushing 60 degrees.I shut down bionic and went back to about 40-42 degrees. I was wondering whether on an air-cooled system whether there is a 1 to 1 ratio between air temp and cpu temp? |

| 311192 | 2005-01-06 08:48:00 | If everything else is constant, then cpu temperature will follow ambient air temperature, or, more exactly, the temperature of the air surrounding the cpu. That is another reason for good case ventillation, to remove the hot air coming off the cpu heatsink, aiming to prevent re-circulation back into the cpu fan intake. |

| 311193 | 2005-01-06 09:06:00 | just to add.......the hotter the ambiant air the less efficient the cooling becomes. ie the hotter the air gets the harder it is to cool something with it. | tweak'e (69) | ||

So your saying that if the air temp went up 10 degrees then the cpu would go up more than 10 degrees correct? |

| 311195 | 2005-01-06 09:33:00 | roughly......tho i don't know how much it would go up and it would vary a bit on the design etc. | tweak'e (69) | ||
| 311196 | 2005-01-06 09:46:00 | if your in doubt buy another fan or cut some exhaust holes, fans are dirt cheap these days..... | Prescott (11) | ||
| 311197 | 2005-01-06 09:55:00 | I'm not worried just curious and I have enough fans. It was just the hot air temperature today which caused the cpu temp to rise. | Raikyn (6293) | ||

Why are you not worried, at least minorly. A CPU is like any other type of Physicall Engine 1 overheating experience is all that is required to inflict permanent damage, its just the degree of noticable damage in the first few occourences. Like some of the threads from time to time about the overclocked CPU'S that are inconsistent/not performing at overclocked speeds any more, WHY?? these people ask. For this reason buying used cpu is allways fraught with danger, especially if its a commonly overclocked model. D. |

| 311199 | 2005-01-06 11:42:00 | Just to ramble on... i got a phonecall a couple weeks ago,seems this persons comp was making noises, suggested to them it was the fan and it needed to be looked at. They said sure sure. Today they ring,say the noise went away but now the comp switches off after a few minutes. I say bring it in,I fire it up and the cpu fan is indeed not moving. I throw a new fan in her,Its all good, I check the bios and the shutdown temp was listed at 110c.......... |
