| 271902 | 2004-09-14 04:03:00 | > Dont worry about CPU temps, the methods used for measuring temps are notoriously inaccurate, they're mearly a ball park figure. Temps can have a variance of up to 10 degrees just based on the motherboard used. Does this refer to the internal diode temp. within the CPU die, or the motherboard sensor? My motherboard sensor reports a case temp. of 42 degrees C, a 'CPU' temperature of 43C and the internal diode temp (via MBM5) is in the 50s. Is this still normal? (The ambient temp. of the room is usually in the 20s.) Just wondering whether it's worth getting an 80mm case fan - but this will mean more noise. |

| 271903 | 2004-09-14 04:12:00 | The motherboard sensors are really bad, and the internal diodes are also known not to be 100% accurate. There isnt really an accurate way of finding your CPU's temp, the internal diode is the most accurate, but still wont be spot on. >Just wondering whether it's worth getting an 80mm case fan - but this >will mean more noise. What CPU do you have? Are you using the stock HSF? Do you have any other case fans? One way to get around noisy fans is to use larger fans and volt mod them. A 120mm fan running @ 7v will push the same amount of air as a 12v 80mm. But because its running slower it make less noise. One of the best fans avaliable in NZ are the Evercool aluminium frame 120mm, they have no mechanical noise and when running at 7v have very lil noise caused by the moving air. |

| 271905 | 2004-09-14 05:13:00 | A Gigabyte GA7-N400Pro2 with a 2800+ on stock cooling is running at 40°C - 50°C (load) here. That's with Artic Silver 3 instead of the thermal pad. 65°C is pretty hot and although it won't damage the chip in the short term I would still invest in a better heatsink and some quality thermal paste. Probably that thermal pad that is causing the excess heat along with the case temperature and no exhaust fans? |

| 271906 | 2004-09-14 05:22:00 | > What CPU do you have? Are you using the stock HSF? Do you have any other case fans? Oops - forgot to mention: AMD Athlon XP 2600+, GlacialTech SilentBreeze 462 II HSF (although I had ordered a 462 III - long story that I'm not sure is quite over). No other fans except for in the Zalman 300B-APF PSU. The case is a Procase PC-309, but I have not installed the side-mounted funnel that fits over the CPU. There is still a side vent in the case at the position of where the funnel goes. I have looked at the spacing of the screw holes on the back & they look as if they are spaced for 80mm fans - not sure how I'd fit a 120mm fan there, unless the screw spacing is the same by some feat of engineering. How does a Vantec Stealth compare to Evercool? |

Hmmmmm seems funny that Pillar showed up very soon after Kiki was banned and has a similar system :D If it doesnt fit then case mod it :D The vantec stealths are good but dont push alot of air and arent exactly quiet. If you want some nice 80mm's have a look at the new Thermaltake Silent Cat, otherwise if your really keen import some SilentX fans from the US. The SilentX fans are second to none in terms of quietness. |

| 271908 | 2004-09-14 05:41:00 | acording to the procase site it takes a 90mm rear fan. i simply doubt the nice quiet zalman will pull enough air through to cool the whole pc properly and with no rear fan it will be sucking air from the outside via the rear fan vent, so the rest of the pc will have minimal airflow over it hence the over heat. install a rear fan, varible speed is best if you want to keep it quiet. i would also block off the side vent....you shouldn't really need it and it wil queiten up the pc a bit. |

| 271910 | 2004-09-14 06:56:00 | I would love to see mine run at 45-50C can using Artic Silver make that much difference??? I have two case fans, one at the front and one at the back. |

| 271911 | 2004-09-14 08:41:00 | i have a thermaltake hardcano12 with one of the probes thermal taped to my cpu s heat sink.finding exactly 10 deg dif between what the system reads and what the probe reads.so the system reads 10 deg hotter than it really is.must be a safety feature. | ferrite (4221) | ||
