8800GTS too hot
E6750, Gigabyte P35C-DS3R, Ausu 8800GTS 320MB, ADATA DDR2 2GB, CoolerMaster
Elite332, Seagate SATA 320GB, PCI modem, no OC, the case only has a 12cm fan at the back. Right after boot, CPU at 44C, system at 56C, 8800GTS at 68C with fan 60%. Few minitues later, others unchange except 8800GTS rised to 74C. I didn't let it go further by switching the fan to 100% then it dropped to 67C (could be lower if I keep on running). At 74C, the airflow exit at the back of the GTS is too hot to touch. I wonder if I should let it run further. The above is just a 2D reading!! My question: 1. is the GTS too hot? 2. will adding a 12cm fan at the front of the case help? 3. how to permanently make the fan run at 100%? Now the fan control software such as Asus Smartdoc, nTune, RaveTuner have to run at start up to do this. I do not use their other functions, so trying to avoid running them to save overhead. Thanks in advance. |

I wonder if I should let it run further. The above is just a 2D reading!! Everything avove 62C or so is too hot too touch. Semiconductors can still be fine, depending on the concrete chip in question. If this chip has similar maximum temperature to current CPUs, then it will take something around 90C and still have a reasonable lifetime of 5 years or so. My question: 1. is the GTS too hot? I actually do not know. I have been wondering the same thing. My fan is on automatic. I expect it will spin faster if the card gets too hot. 2. will adding a 12cm fan at the front of the case help? Depends. The cooler design is exceedingly stupid by blowing a major potion of the hot air inside the case. I have re-reouted the air for the moment (PVC tape) and this at least makes the other components run cooler with, so far, no negative evvect on the card. However I have seen up to 75C card temperature with the case open at 22C ambient temperature. My guess would be that the fan will not help the card, but the rest of the computer. 3. how to permanently make the fan run at 100%? Now the fan control software such as Asus Smartdoc, nTune, RaveTuner have to run at start up to do this. I do not use their other functions, so trying to avoid running them to save overhead. The question is if this is neded. My card has 3 years warranty. If it kills itself, not really my problem. If it kills other stuff by heating up the computers inside, very much my problem. Another reason tpo re-route the hot air to the outside. Arno |

I wonder if I should let it run further. The above is just a 2D reading!! My question: 1. is the GTS too hot? The only temp that matters is the fully loaded 3D temp. Run the fan at 100%. Turn on the hardware monitoring strip charts in Rivatuner and launch a stressful game (Bioshock is a good one). Play for about half an hour, exit, and look at the peak temp. Don't worry about damaging the card as it has thermal shutdown capability. If the peak temp is below 90C you are fine. Modern cards are designed to withstand that kind of heat. 2. will adding a 12cm fan at the front of the case help? I think it'll help a tiny bit, say 5C improvement. Your case's side panel already has a vent in the expansion slot area, so the video card fan shouldn't be starving for cool air. Take a temperature reading with the side panel off. That's as good as it gets for case ventilation. 3. how to permanently make the fan run at 100%? Now the fan control software such as Asus Smartdoc, nTune, RaveTuner have to run at start up to do this. I do not use their other functions, so trying to avoid running them to save overhead. I think you can exit Rivatuner after Windows startup and keep the fan speed setting for the duration of the Windows session. A more permanent solution is to run the fan directly off a 12V lead from the PSU (using a 34-pin adapter. You can also solder the fan wires to a 12V pin on the card's 6-pin PCIe power connector, but that'll of course void your warranty. -- "War is the continuation of politics by other means.

8800GTS too hot
Your case currently lacks adequate cooling for your chosen components which
produce a lot of heat. At a minimum, yes, add a front case fan. See if that gives adequate temps afterwards. -- --------------------- DaveW --------------------- "senderj" wrote in message ...
