Does the 8800GTs have a generalized heat problem ?!?!

Hi,

Last week, I sold my evga 8800GTS 640 (300$) and order a evga 8800GT Superclocked (284$ !). So since then I'm waiting for my shipment and read many post on different forum talking about heating problem. Most of the time the answer to the problem is something like "Download Rivatuner and set the fan speed to 100%" ... no big deal. But sometime it doesn`t seem to solve the problem. I even read some post where the only solution is to underclock the memory !!! Wow ... I begin to freak out ...

So it would be nice if the 8800GT user could post some stats about their fan speed/temperature/configuration.

Thanks !
 
Might want to remove the heatsink, clean it, and replace the TIM with AS5. There are a couple topics on the [H] forums with pics that show how sloppy the thermal "clay" is applied sometimes.
 
Mine overclocks to 700/960 w/o any problems.

My default speeds are 650/950.

My memory hardly overclocks at all. At 965Mhz I see artifacts and even lock ups.

How's it going Ed, the only problem with the 8800GT is the default fan speed which is why you see everyone recommending Rivatuner. At defaults it spin at 29% at idle which is fine really, but only ramps-up to 35% under load. At these temps most users and reviewers are getting 60c at idle and 90c under load. The card is usable at these temps, but most prefer their cards to be a bit cooler. Setting the fan using Rivatuner to 50%-65% will generally drop things down to a more comfortable 48-52c at idle, and 62c-68c under load. Those are my temps as well and overclocking my SC EVGA to 700 Mhz. core. So once you get you card use Rivatuner to monitor your temps and see what's best for your system and your ears.

As far as the individual that's saying he needs to drop his memory clocks make his card stable. I've seen that person's post and he definitely has some other issues which he hasn't addressed.
 
i run 2 in sli

my fan at 60% on both cards when I game, the only games that make the cards go over 70c is crysis and bioshock sometimes, everything else loads them in the mid 60's for me. I have excellent air flow though in my ghetto armor full of 120 yates
 
Thanks for your replys. 70C That's not too bad. My GTS 640 was around that temp.

You do realize Hardforums is part of Hardocp, Hardocp does video card reviews, just like the one you bought, which shows it at roughly 80-90C load....

Also, wtf, switching an 8800gts 640 for an 8800gt? is there really any reason why you did that?
 
I did that with my other computer. They are faster and cheaper. I actually made $50 USD when I upgraded.
 
Ok noob question here...but would running your fan at a constant 100% shorten the life of it at all? I should be receiving my 8800GT Superclocked tomorrow and I read the tutorial on how to set fan speed profiles and got them to work on my current 7900GT. I was only asking because when you set fan control at low-level and then (by the tutorial) you set your fan speed profiles, 100% is the last one created and from what I understood it stays at 100% until you start playing a game. Am I misunderstanding something here? Can you set it back to say 60% after creating your fan speed profiles? Thanks for any advice

It's "piss" not "pissed" and there's no need to push buttons here.

All fans are designed to run at full speed 24/7/365 for the life of the fan.
If you run your card at 100% ALL the time you are a crazy kid, the noise alone will make you wanna shoot yourself.
Just monitor your temps during idle and load and see how it is first. If your temps are within acceptable ranges just leave it.
 
Aye...I was kinda thinking the same thing. My fans are loud enough already lol.

One of my 8800GTX in SLI runs hot and the fan is normally at 60%.
I use RIva Tuner during games to bring it up to 80-100%.
You can manually set it back using the default on the Riva Tuner or it will go back to default when you reboot the computer also.
 
8800gt ssc fan @ 78% all the time, 53 idle 70-75 on full load. Why 78%? Because its just before the fan gets too loud for me :)
 
The temps on the 8800GT GPU that we see are higher than what we're used to, but there's no reason to believe that it's a "problem."

8800GT = faster than 8800GTS in the majority of situations. Also, if he sold his GTS for MORE than the GT cost...well...that's a no brainer.

I sold my 640mb GTS for $205, and paid $269....so what, I am happy. It DOES perform noticeably better.

If you stay at 85c or less, you are GOLDEN with these cards, and actually, they can live a long life at 90c.....just think how hot one of them runs in a quiet low airflow OEM box....

My personal 8800GT was load tested at 104c-106c for over an hour.....I had the fan speed locked accidentally at 29% :eek: and it never ramped up with heat.
 
Hmmm...it said there was a driver issue with RivaTuner after I booted my PC up after installing the latest drivers. Should I reinstall RT as well?

Edit: Tried reinstalling RT but it said once again that RT may not work correctly due to the drivers being a newer version that what RT was tested with. It's showing the temp idling at 49-50c but the fan is shown to be running at 100% speed when I have it set to 70%... Any ideas?

RT just does not recognize a newer build of driver, but it still works fine, that's normal since RT is older than the driver you are using. And the fan thing showing at 100%, I get that too...can;t find a way to make it show true fan speed, but if you set your fan speeds to ramp up and down with temps, it works perfectly. http://www.vaguesoft.com/users/dwood/blog/tutorials/rivatuner/
 
I haven't set any fan speed profiles up but I did set the fan to run at a constant 70%. I got Crysis tonight and at 1280x1024 and all settings at high it never got any higher than 72c. Should I go ahead and set up fan speed controls or just leave it as is?

I would. If anything just set one that ramps it from 40% at idle to 70% once it hits 70. That way it's whisper quiet when not gaming and it cools well when gaming and noise isn't a problem. Unless you game in silence. ;)
 
On my eVGA 8800GT KO, idle is 52 C and load under Crysis is 82 C. It's a bit high for me as I used to watercool my 1900XT 512MB and the highest it got was like 55 C. I'm going to slap on a waterblock tonight and see how much a difference it makes.

Same for me ... more performance for free ! Also ...I was about to buy Quake Wars .. and it is bundle with the card ! That's a no brainer indeed.

Exactly, knock the $50 purchase price for Quake Wars and it's a great deal. I was going to pick it up myself and it was included with my card.
 
The 8800GT is rated to insane GPU core operating temperatures, and mid 80's to mid 90's (celsius) is the norm with this card.

People that have to increase the fan speed or underclock their cards to get rid of artifacting at stock speeds (no matter WHAT the temps are) have a defective product and should return it or RMA it.

OP, you need to keep in mind that people RARELY take the time to post on a forum about how much they enjoy their video card. Most of the posts you see will be complaints from those unfortunate few that got a bad card and you should keep that in mind when reading any forum.


My 8800GT? It's an Asus branded board and it runs normally in the mid 80's at load at stock speeds. However it will overclock to 720/1060 completely stable... :)

As long as you can stand the noise, it doesn't matter. My profile keeps my card less than 85c, and the fan never goes past 55%.
 
I run two BFG oc cards in sli and have not touched fan speed. I have good airflow and have not had any heat issues.

This is totally true ! That's why I asked some feedback.
 
Hey I have some questions
If I take the stock cooler off, would I only need to cool the ram and core or are there more chips that need to be cooled? how many ramchips does the 8800gt has

What are good ramsinks and a good core heatsink cooller that fits the 8800gt?

You have the core, the 12 RAM modules, and the PWM modules to cool. In my case, I ran out of ramsinks so I have my PWM modules exposed. But, with a PCI-slot dual-fan setup, my temperatures are: 26 C idle (core), 26 C idle (RAM0, and 30 C idle (ambient), according to Lavalys. The core temperature from Rivatuner v2.06 reports it higher at 34 C idle.

woah 12 ram modules, how many pwm modules, and are they easy to identify?
I'm upgrading from a geforce 5900fx, didn't need to cool pwm modules

EDIT: My mistake, it's actually 8 memory modules. =P
 
I am waiting for my 8800GT as well.

Questions:

1. I am sure most of you OC your 8800GT, how are the temperatures if you don't OC?
2. Never used RT before. Can I set the fan speed dependent on temperature of the card?
