"Sydtech" wrote in message ... "~misfit~" wrote in message ... I'm wondering about your case temps. You can have the best cooler in the world but it it's trying to dump heat into an already warm environment it ain't gonna do squat. Right now, the case temp is reporting at 28C, and the CPU is reporting at 48C. I'm using Speedfan, and I've got the CPU fan set at 80% and the NB fan set at 35% - this seems to me to be an acceptable balance between noise and cooling. The fan is a stock Antec Sonata, with a single case fan in the back. I've got the cables arranged neatly out of the way so they're not getting in the way of the airflow. At this point, I'm suspecting that maybe the Abit IC7-G is reporting temperatures that are higher than they actually are...after googling around a bit based on j's post, this does seem to be a problem with this particular moboard. I also saw another post somewhere suggesting that the Zalman needs to be installed in a specific orientation - that it's possible to install it flipped around the wrong way, causing it to sit off-center of the CPU. Based on what I've seen, I'm not sure this is true. There's only one way to find out, but I'm waffling over whether I want to yank the Zalman out, clean it off and reapply the Arctic Silver, and reinstall. This process was such an enormous pain in the ass the first time that I really don't relish the thought... j didn't realize he was j untill after he posted. He now believes that when switching to his other comp he should verify exactly who he is before posting. In any case j will be heard from no more. Looking at my Zalman ( though I can't examine it very close as this comp is placed ) I don't see any way to put it on wrong. I believe if you set the cpu and north bridge fans to 100% this will help to solve the problem. Maybe I'm old fashioned but I see no purpose in those bios settings which reduce fan speed other than to increase the likely hood of your comp over heating. There are better options in the way of making a comp totaly silent then by turning the fans down. If I read you correctly you only have one case fan? not good. As I stated previously If your board has the same problem as the IC7 Max3 then the reported temp is probably higher then the actual temp. I've used three different boards on the exact same rig switching only the boards. The boards being the gigabyte GA 8KNXP, asus P4C 800-E Deluxe and the abit IC7 Max3. The IC7 Max3 reports temps that are 10c higher then the other two boards. The Max3 is not the only abit board reporting temps wrong. I can't say for sure that your board is one of them but it probably is. Also how much the reading might be off might depend on how a particular setup is configured. As far as I understand abits position on this they seem to believe that the calculations they use to produce the temp reading is in fact the correct way of calculating the temp. This of course could be correct I personaly do not know. I do know however that if there method is correct it would mean that other board makers are doing it the wrong way. Many of us abit users do not believe that this is the case. |

I had been disappointed with the average performance of the Aero 4, so I ordered the top model Aero 7 - 478 (not socket 478!). This is an Aero 7 with heatpipes, which was not available in Europe and had to come from Japan. Tested in exactly the same circumstances as the stock Intel and measured with Asus Probe, the results were as follows (for an ambient temp of 20°C): Idle mode: Intel: 29°C, Aero at 60%: 29°C, Aero at 100%: 28°C Stressed: Intel: 43°C, Aero at 60%: 42°C, Aero at 100%: 38°C I've tested many coolers, and this last figure is the best I got with "off-the-shelf" coolers. However, at 100% rpm, the Aero is very loud, and that's why I finally decided to switch to a home-made assembly (ThermalRight CU cooler with papst 120 cm fan). In stressed mode, I get only 2 °C better than the Aero at 100% rpm, but it's really quiet! |

They do it for lower noise as not everyone is seeking "better temps." Exactly. I'm not interested in having the absolute lowest temperature possible; I just want a semi-quiet machine without cooking the CPU or chipset in the process...the stock CPU and (especially) the Northbridge fan on that IC7-G were just screaming in my ear. The combination of the Zalman and Speedfan are alleviating that somewhat...although I'm still not sure whether my lackluster results from the Zalman are a result of an imperfect install or the motherboard misreporting the temperatures.... I wish I could help you but that kind of thing really needs the ability to look see. |

CPU temperature is dependent on several factors:
o Heatsink performance re oC/W o Fan CFM and that realised over the heatsink surface area o Limiting the recirculation of heated air over the heatsink ---- which is a system-level issue I suspect the latter may be a factor in your readings. Additionally, recent Intel heatsinks are not bad - they are well engineered for their end-price in terms of Flotherm/CFD/FEA. Noise isn't so great on the Xeons, but that's more re 60mm/2U. Heatsinks fall into 2 types: o Impingement -- fan blows down to impinge on fins on a flat plate ---- higher airflow recirculation 40-70% ---- eg, SLK - but uses heatpipes to speed heat-transfer from the CPU o Blow-thro -- fan blows air along fins - straight thro v 90-degree ---- lower airflow recirculation 20-30% In reality recirculation also depends on the *system*. o If your exhaust fans aren't removing CPU heat fast enough o So *any* heatsink will recirculate correspondingly more hot air Hence AMD-certified-PSU put their intake near the CPU cooler :-) If your CPU/System cause the heatsink/fan to recirculate 50% of the airflow then whilst 15cfm is enough for CPU watts, you need 30cfm. To ensure good thro-case airflow: o Cases with slotted/punched exhaust fan grills restrict airflow ---- 80-85% of all case airflow resistance is from PSU/Exhaust fan grills ---- replacing them with round-wire grills drops the figure to 14-16% o Exhaust fan on the case near the CPU ---- exhausting hot air from the CPU-cooler before it can be recirculated So there are many factors to consider. There's a simple check you can do: o Identify your baseline HSF oC/W at the fan cfm you have ---- eg, 0.25oC/W o Identify your ambient temperature near the CPU fan ---- more difficult, chipset board temp isn't very accurate o Identify your thermal CPU output ---- easier to do with 100% CPU load, ie, P4-3.06-HT-533 is 75W o From this work out your *realised* temp-rise per wattage ---- CPU-temp less Ambient-temp / CPU wattage ---- eg, 0.4oC/W That gives you an idea of how much hot air is being recirculated in *your* implementation of the HSF in the case/intake/exhaust system. Personally I would say the Zalman flower are for absolute low-noise at economical price, and the SLK are for absolute overclocking at a higher price - mainly by virtue of the heatpipe technology they also use. BTX will introduce fanless heatsinks with blow-thro cooling, altho I expect PSU & Case fans to be as if not more important due to the eventual ramp in yet higher graphics card outputs, RAM speeds & outputs (30W), VRM outputs (for both CPU *and* RAM) etc. Intel heatsinks aren't particularly bad - altho Prescott produces a very high thermal output which stresses 1) heatsink and 2) chassis. The importance of chassis airflow is very apparent with Prescott: o The CPU is 103W, so ran (very) hot with heatsinks 60-65oC o The motherboard CPU VRM capacitors ran 235F ---- that is above common 105oC & even mil 125oC specs o Of course the motherboard was in free air :-) ---- so illustrating how important chassis cooling will become Important to consider PC cooling as a system as watts rise. -- Dorothy Bradbury www.stores.ebay.co.uk/panaflofan for fans, books & other items http://homepage.ntlworld.com/dorothy...ry/panaflo.htm (Direct) |
