| 209910 | 2004-01-26 04:10:00 | My thought was that case fans will help with cooling of the CPU. But - very good point you made about the ram/harddrive etc. as I never even though about them. I think I'll monitor the case temperature for a few days and see what happens - if the case temperature is too warm, then I'll look at investing in a (quiet) case fan. |

| 209911 | 2004-01-26 04:19:00 | > why do people quote cpu temps when they are dealing > with CASE fans??? Because, imho the CPU temp is not in disparity with the temps of other components, and it's the most sensitive of them all to excessive heat, so whatever case cooling methods are employed, the primary function is to keep the CPU temperature down. I've yet to read on any overclockers forums of the same amount of extra cooling being applied to other componentry than to the CPU |

| 209912 | 2004-01-26 19:43:00 | The case temperatures have remainded very reasonable, and have only changed about 1 or 2 degrees compared to when I had the case fan. However, the CPU temperature has risen about 5-6 degrees, to 40degrees when there is little load on the CPU, so I think I might need to go buy a (quiet) case fan to try to help. | somebody (208) | ||
| 209913 | 2004-01-26 20:56:00 | you can get that exspecially when useing "non-amd type" psu's ie ones that don't have fans or air vents on the underside of the psu case. hot air can pool under the psu so the cpu fan just sucks in warm air all the time. | tweak'e (174) | ||
| 209914 | 2004-01-26 23:47:00 | The PSU I have does have vents in the proper places, although the PSU itself seems to get very hot. | somebody (208) | ||
| 209915 | 2004-01-27 00:13:00 | It's an irritating facet of my case design too. I'd prefer the PSU to be right at the top and for the rear case fan postion to be underneath it, next to the CPU. Even though my PSU has dual fans and so is supposedly not adding to heat build up near the CPU it does generate heat and my 80mm case fan pumps more air through than it does. Also, even with binding up the power cables coming from the PSU there's still a lot of wires there to block the airflow to the case fan above. Having been looking at this now for a week or so (I'll be writing about it in the March issue) it's become obvious that one of the smartest things you can do up front is spend extra money on a good PC case when building your PC -- not because it looks cool but because a good case has much better design inside for cooling fan placement and more places to put those fans too. Not to mention large side locations for fans and vents right at the top. Even though I've now installed a range of different fan options from a whole swag I got in to test, the design of my case prevents me from using some of them. Best little toy I've got so far is a thing called the Digi Doctor which installs in a 5.25-inch bay and has (up to) 8 sensors attached to it for measuring heat in various locations in the PC. But you also run your fans through it and each fan can then be married to one of these sensors, and told to start up when a certain (you select) temp is reached. So, for example, you can have a fan down by your video card that only kicks in when you start playing a game and the card starts working hard. |

| 209917 | 2004-01-27 10:03:00 | Here here tweake & Bruce.... either that or we could do what AMD UK did last year & cool the CPU with LIQUID NITROGEN & overclock it to 8Ghz - apparently it lasted 45 minutes before sufferring a non-passive end-of- life failure (the magic smoke demons escaped !). | caveman (3231) | ||
| 209918 | 2004-01-27 21:54:00 | >they are only any good if correctly used. in some situations they are a drawback. Which is also the problem with some of the add in fans ideas I've been testing. Slot fans, fans that install in the 3.5 or 5.25 bays and vent out the front, etc etc. Some of them work quite well but all of them will undoubtedly disturb the airflow in unpredictable ways which can lead to pockets of hot air where there weren't before. I've found they can be quite good in venting air from other components but you've really got to keep and eye on the temp near the CPU because if they are taking cool air away from there then you're really not helping at all. |

| 209919 | 2004-01-27 22:00:00 | and the other catch of any rear inlet fan setup is they can suck back in the hot air that just came out of the pc. same goes for some of the side vents. | tweak'e (174) | ||
