Radeon 9700 PRO - How hot is 2 hot?
I have a physical disability that sometimes keeps me in bed most of the day.
As a result, I recently decided to build a PC for use from bed. Given that it is likely to be my primary use PC, I wanted something with a little power. I decided on an Intel D875PBZ (Bonanza) motherboard with a 2.6 GHz Hyper Threading P4 (800 MHz FSB), 512MB PC3200 DDR, 120GB Maxtor ATA/133 7200 RPM 8MB cache hard drive. For sound I went with an SB Audigy 2, and for video I went with an ATI built Radeon 9700 PRO 128MB. The flip side is, being a mere 18" away from my pillows, I also wanted to build a QUIET PC - hopefully the quietest PC I had ever built, despite its muscular nature. Accordingly, I built the system in a Lian Li PC-6070 case which comes with two oversize, low-speed front case intake fans, an oversize low-speed rear case exhaust fan, sound insulation material on the sides and top, and (to help with CD/DVD drive noise) a thick aluminum door on the front with "weather-stripping" to prevent sound leaks. I installed an Enermax Whisper power supply with a manually controlled exhaust fan (which I run at lowest speed). The Maxtor hard drive has fluid dynamic bearings, and I purchased my DVD and CD recorders with an eye to quiet as well. Finally, and probably most significantly sound-wise, I replaced the "stock" CPU and GPU fan/heatsink assemblies. Using Arctic Silver 3, I installed a Zalman CNPS7000-Cu - a truly wonderful heatsink. I run the fan on the Zalman at it lowest speed, and it still keeps my processor five to ten degrees cooler than the OEM fan/heatsink. On the 9700 PRO, once again using Arctic Silver 3, I installed a Zalman ZM80A-HP. I believe that I did a clean, competent installation of the ZM80A-HP, but I remain a little concerned about it. For instance, the instructions for the Arctic Silver 3 compound stresses the fact that the thinnest layer of compound that actually "fills the gap" gives the best cooling performance. On the other hand, the instructions for the ZM80A-HP warn that, due to video card/GPU design, there may be a problem with the heat sink transfer block seating against the GPU, and that you may need a thick layer of heat transfer compound. As best I could tell, on my Radeon 9700 PRO the heat sink transfer block seated cleanly against the surface of the GPU, and for that reason I tried to keep the transfer compound layer fairly thin. I am concerned, however, that the GPU may be running hotter than it should be. According to the Intel Active Monitor software, my processor is running 104F/40C , the ambient temperature sensor integrated in the hardware monitoring ASIC reports 100F/38C and the remote ambient temperature sensor reports 99F/37C. Both of these sensors are mounted on the motherboard, fairly close to the processor socket. In addition, I have a Lian-Li T-3, which has two thermal sensors that can be placed wherever the installer wants, and two LCD displays. I have one of the thermal sensors positioned in the middle of the intake airflow "after" the hard drives which reports 88F/31C. The other thermal sensor I positioned so that it resting on the side of the GPU heat sink transfer block - NOT between the transfer block and the GPU - and this is the one that worries me. Not running any 3D applications whatsoever, this sensor reports between 125F/52C and 135F/57C. This is just running Internet Explorer, Outlook Express, Word and other productivity apps on the Windows XP desktop. This seems pretty hot to me, but I am not sure what kind of temperatures the 9700 PRO GPU is intended to operate at. I am not currently overclocking either the system or the video card, and I have no driving desire to do so. On the other hand, I am going to start loading up some 3D games before long - and I expect that exercising the 3D capabilities of the GPU will cause it to run even hotter - right? I haven't seen any problems with the display so far, but I have had one "blue screen" that reported that the video driver was in an infinite loop - something I thought might just be caused by an overheating GPU. I know that I am getting - at best - an estimate of the temperature of the GPU heat sink - the GPU itself may be running much hotter. Is there some good way to tell how hot the GPU on an 9700 PRO is running? How hot is it safe for this GPU to run? Does anyone else have experience running the Zalman ZM80A-HP on a 9700 PRO? Will I absolutely need to mount a fan to blow on the ZM80A-HP in order to keep the GPU cool enough once I start playing games? How do over-clockers determine if their GPUs are getting too hot - just wait for the card to "fall over"? Is running this hot going to shorten the live of my video card? Thanks for any and all information. This is the first time I have done any "modding" - in the past I always just put the parts together and powered up the system. I have to say, I LOVE this PC. It runs as quiet as a whisper - sometimes I have to check the lights to see if the system is running or in S3 standby! |

my 9700pro runs at about 50 deg C idle
thats taken using the card onboard temp sensor (its a Tyan board with hardware monitoring) |

Thanks for the pointer - I appreciate the information. Unfortunately, I
didn't find anything about thermal issues in this article. I was hoping that along with performance the author would report on the temperatures of the Gus using the two different cooling solutions (the ATI stock solution and the Sapphire/Zalman solution) while the GPU was being exercised. Perhaps if I had known about the existence of the Sapphire/Zalman cares I would have bought one of them instead - but that is a moot point now. I have my 9700 PRO and I have my Zalman ZM80A-HP. What I need to know is whether my ZM80A-HP is doing a sufficient job of cooling my card in my installation. The ZM80A-HP relies on system air flow, I'm not sure my system is moving enough air. Regardless of the size of the heatsink, the heat needs to be "blown away" at some point. I need to know how hot the GPU can operate "safely" - and I need to know how to determine how hot my GPU is operating. "MrMoke" wrote in message ... I know this isn't a quick answer, but should answer most of you questions regarding Zalman technology and Radeons. Maybe you should have looked at one of these before operating on a made by ATI card. They don't make them any quieter, or fatter See: http://www.beyond3d.com/reviews/sapphire/ults/ "Thom Culbertson" wrote in message news:G_hUa.145789$ye4.100530@sccrnsc01...

yeah, stock heatsink/fan. not overclocked.
hopefully tomorrowe (monday) i'll have a game (c&c generals with any luck ) and take the temp right after that for you Regards |

ASFAIK 60-70 degrees C for a CPU and GPU should be within spec, so you
should be Ok. |

Just took the temp, and mine gets up to about 56 deg C during a 40 min game
of C and C generals. |
