I wonder why his card is only have 29% fan on idle? Mine sits around 40ish% and idles are 50C.

Is the BIOS flash an app from the card manufacturer? where do you obtain this at? just curious for future use.
 


I have tried three different 8800GTS G92 from XFX, eVGA and BFG. The fan profile of XFX is different from the other two. XFX uses "Automatic Speed" fan profile while the other two use "Dynamic Speed" profile.

Basically, XFX's fan profile is more aggressive than BFG&eVGA. That's why it can achieve lower temperature. But XFX also gives out more noise than the other two due to high RPM of the fan especially at load.

You can hardly hear any noise from eVGA and BFG while at load since their fan remains around 37% duty cycle at around 70 degree C. For XFX, it will run at 100% duty cycle@70 degree C.

You can change these parameters with NiBitor.

 


I actually like how my XFX is throttled. At idle I can't hear a thing to tell you the truth and my case fans are really quiet. The only time I every hear it is during a game and it kicks on. It has never exceeded 65C so i never gets to that 70C 100% mark. Probably never will either.
 
Awesome, I'll have a look at NiBitor and report back with the results.

I'm a bit confused about changing the temperature thresholds for the fan speeds using Rivatuner so I'll have a look at this.
 
A lot of people are down on VGA coolers that don't exhaust heat out the back of the case. It sounds like a logical argument that would make a lot of sense. However, in practice, my Accelero S1 with turbo modules on an overclocked 8800gt in a Cooler Master Elite 330 case idles at 38C and loads at 44C. The Q6600 @ 3.2ghz with a tuniq tower in this same case idles at 28C and loads at 58C with the fan on low. My point is that in a case with good airflow, the heat is going be carried away and low temps on vital components can be achieved without VGA coolers exhausting out the back of the case. Just my observation...
 

Thats a valid argument. I never noticed an increase in CPU temps, I did on my mobo though. When i went from my old x1900xtx and thermalright cooler tomy GTS my mobo temp went down 5C
 
After my successful BIOS flash, my idle temps are 61 degrees and it went up to 79 degrees under load. The fan didn't go very loud so I suppose I didn't set it aggressively enough.

The scary thing was that my CPU now reached 67 degrees on one core (65 on the other), something which I've never seen before. Seems like the ambient temps are way too high, there should be a cooler on top of the card too, or something pulling the air out from right above the card.

I think I'll get a third party cooler, this is just getting ridiculous. I have a fan controller which I will just have to turn a switch on to make it from totally noiseless to practically silent (with the right fan and an Accelero S1).

Check out the praise for the S1 here: http://www.hardforum.com/showthread.php?t=1261100&page=10
 
I've never gotten too worked up over motherboard temps. Are you talking NB? Or the random sensors some MB manufacturers place on the boards? In any event, I've never really had a MB go bad on account of temps or had performance affected in any way. I'm not arguing that the GTS has a bad cooler by any means, but I just see coolers like the Accelero S1 and Zalman VF series getting knocked for not exhausting out the back of the case. I never really understand where these arguments are coming from as I see fantastic results and silent operation.
 
I was refering to the NB temp. I know what you mean by exhausting vs non exhausting. I can see if you don't have proper air flow it could be an issue with maybe your CPU, but who know. I still say the GTS stock cooler is much better than the stock GT cooler. I do like the MSI Gt cooler though. I also did not feel like messing with a cooler for my GTS because it really didnt show VAST improvements when overclocking.
 
If my GTS cooler would work the way that other people's coolers do, I'd be happy. I reckon an Accelero S1 with a few cleverly placed fans would to a good job with exhausting too.

Does a high NB temperature bring anything negative with it anyways? I always hear people freak about high temperatures but I've never had any problems myself. HWMonitor shows me TMP01 and TMP02, I' guessing TMP01 is the Northbridge.
 


I really doubt it. I have a feeling if you have a higher overclock on the CPU it might hinder you a bit because you are overclocking the bus in order to achieve a higher clock.
 
articsilver5 paste in itself does a great job! try and just replace the goo on the stock HSF with articsilver5 and see if that doesn't bring the temp down a bit.
 

I've done some self experimenting with AC5 and I have not seen any proof that AC5 is any better than any other thermal paste. People always report that it helps to remove the stock goo and reapply AC5. However I challenge people to remove their stock grease and just use any good grease other than AC5. I got a large tube of Thermalright paste that game with both my current CPU cooler and my GPU cooler from my old x1900xtx card. I've gone between this and a little tube of AC5 that I had and There has never been any change in idle or load temps on my CPU or old GPU. It was the EXACT same.

My thought is from the factory they use either a machine to place a glob in the middle and the pressure itself to spread it around. Or they use pre-made pads that melt in place. Removing and uniformly spreading any decent paste on the contact surface will work better.
 
doubletake33: I did already, I was mistaken when I said that I used Arctic Silver 3, it's Arctic Silver 5.

jay2tall: The stock thermal conducting is undertaken by horrible thermal pads.

Also, whilst I am overclocking the BUS, my overclock isn't anything spectacular when comparing to others so it shouldn't hinder me much.

I fried my motherboard two days ago so I'll look for another motherboard, hopefully with more clearance to the CPU. The DS3R puts the GPU and NB too close to the CPU in my opinion, there just isn't room for any heat to leave the area. This is assuming that my hardware shop is willing to let me upgrade to a better motherboard.

 
i think thr AS5 would do better if its on a metal surface on both side.but gps is the bare chip that the heatsink is seat on.but on cpu is different since its got a heatspreader.
 
here is my 2 cents on this...the faster the fan is going, the lower the idle temp. the faster the fan is going the harder it is for the temperature to peak. also i've found that after 80% fan speed the temperature decrease versus noise factor is not worth it. so, you can download rivatuner and play with a fan profile like this.

< 64 trending down = fan @ 40% speed, give mes idle temp of about 61
> 66 trending up = fan@ 80%, gives me peak temp of 75

my oc settings are 750 gpa, 1050 ram...

i've been wondering about flashing the bios but i hven't seen a tutorial or step by step...whatever works in riva tuner should work as bios mod... then no software to load to get it done, that's the part i like.


sorry for the reply a year late...found this post while looking into nibitor
