| 1237684 | 2011-10-23 07:27:00 | Another update (long delay, sorry; been a bit busy lately): temp3 corresponds to the SYSTEM (not CPU) temperature on the motherboard, which (now that I have the part number) is Gigabyte GA-M61SME-S2. The CPU temperature problem no longer rises above 55-60'C, but temp3, which corresponds to the SYSTEM temperature, is frequently getting over 80'C. There was no case fan mounted so I mounted one (turns out its about as noisy as a hairdryer so it's not a permanent solution by any means) on the back of the case and decreased temp3 to a respectable 50-55'C. However, the way the graphics card goes in my slot seems to try and defy physics; the fins on the heatsink are mounted so they're pointing downwards and heat is rising into the card. The graphics card has passive cooling so I mounted a smaller fan below the graphics card on a makeshift stand. However while this keeps the GPU cool-ish (I've heard they normally run quite hot, in the order of the high 70's in use) the system temperature is suffering for it as there is only one socket on the mobo for a fan. What I would like to know is what on the motherboard is corresponding to temp3 (i.e. where the sensor is on the board so I know what's cooking) or how I would go about finding out. In terms of the one-extra-fan-only problem I was thinking of wiring the two fans in parallel (one of them doesn't have a speed output so obviously I'll just have the speed output of one going to the mobo, and the speed of the system fan is unable to be controlled via the BIOS.) | mookster1 (15854) | ||

Probably northbridge for system temp Don't run too many fans off a motherboard fan header, they aren't really designed for more than one each. Better to tap directly from the PSU itself with an adapter. |

The graphics card has passive cooling Yes, and they put pictures on that side too - why, when you mount it you don't see it, always thought they should have been installed the other way up...................passive cooling?? Terrible idea for GPUs. |

| 1237687 | 2011-10-23 18:22:00 | +1 for using an adapter for the second fan, also bear in mind that a case fan also helps the GPU by uncreasing airflow. You can get quiet fans, obviously they tend to move less air but that's the trade off. What size fans does the case allow? an 8cm fan will always be noisy to shift a decent amount of air but 12cm ones can do the same airflow with almost no noise. Unfortunately if you can't solve it to your satisfaction with that case the only options are to either mod it for better airflow or get a better case, most modern cases have a 12cm intake and 12cm exhaust fan by default. Mine currently has 3 12cm intakes + 1 12cm rear and 1 14cm top exhaust fans. It's very cool inside the case but not especially quiet :) |

Terrible idea for GPUs. So buy one of those cases that puts the motherboard up-side down... But in any case who cares what's on the graphics card? My last one had some sort of transsexual fairy\elf on the box but I don't care, what's displayed on the screen is more important to me :lol: |
