6950 TF 3 cooler mod..

post #1 of 25
Thread Starter 
Well , I'm happy with the TF 3 cooler but I'm sure It could do better.

Just gave my Accelero S1 rev.2 to ma bro ..
So, was wondering whether there was much that could be done to improve this cooler's performance..

Here's what I propose..

2x90mm Blademasters by Cooler Master ?? I'll just Zip tie them on .. Don't know how to mount them even If I did..
MSI_R6950_Twin_Frozr_III_Power_Edition_Cooler_Removed.jpg
Questions :
1. Is a washer mod a good idea for this card? It can't hurt , now can it ?
2. Any better fans available in :ninja:Delhi:ninja: ~ 80-90 mm ?? Slim preferably.
3. Will putting some additional aluminium mosfet heatsinks on the ram heatspreader help one bit ?
4. The mosfets are sharing heat with the Vram :/ It's insulting frown.gif

Anything else to let me help this cooler's efficiency and noise... thanks!laugher.gif
Shall change the TIM once I disassemble the card.. Don't plan on polishing the heatsink .. Just lapped my CPU but I'm in no mood to do the Gfx card..baaasmiley.gif

I don't want to irreversibly void the warranty on this one , can't afford problems.. It wasn't a problem doing this to my older cards.. but I need this card to stay intact.
UPDATE :

1. Will be zip tying the 80mm CM blademasters onto the GFX HS.
2. Wondering whether pulling air AWAY from the cards would be beneficial .. Not INTO the card.. have a 220mm exhaust side panel fan .. so..
3. It's not just the temps, its the NOISE TOO !! So this mod is a must.. any other ideas for a better /more silent cooling solution ?

To add some more information :

Clocks :
965/1600

Volts :
Core/Mem/Aux
1.245/+30mV/+10mV

Full load temps NOW 75C (OCCT-8) with +20% powertune ..
Shaders unlocked.
(see sig)

Running a HAF 922 with plenty of case fans ..as of NOW , the side panel is off and ambients are 24C ..
Ambients are about to rise to 30 ( Back to the hostel in a week .. so .. )

i would leave it completely stock. Is there really any need for this mod? are your temps bad?

Edit: saw your temps and for that OC i wouldnt call them bad! I would just leave it be and not risk voiding your warranty nor break something in the process!

How do you change other voltages on the HD6950 other than Core? AB got only core voltage for me to change.

Well , thinking .. shouldn't 2 90mm blademaster mean better airflow ? I have the option of a Zalman pci slot blower..

75C when the ambients are 23-24C is OK ..
When the ambients hit 30-35C then what ? smile.gif
And I plan to OC higher too ..

The noise is now becoming unbearable..
Dust is collecting like a w****

The 90mm fans wont cost me a thing ..
I like my card. I just want better..

I'm coming from a copletely quiet solution on my 6850 .. An accelero S1 w/ a pci double fan bearing PCI zalman blower.. that thing didnt even hum tongue.gif

Lookup the link in my sig..

Btw.. its a small dropdown by the Core voltage ..
see the pic here smile.gif .. attached.

How would you mount the 90mm fans?.. And replacing the blades on the fan (if you could) wouldn't really do anything, besides potentially making it worse. As for noise, I'm pretty sure its not that loud even on the higher speeds compared to the reference design.

If you want to overclock higher I suggest going back to 1408 shaders since compared to 1536 at the same clocks you don't gain much performance, with roughly 3-4% in general and 5% at the most and you will get better temps which will mean you can overclock further and gain more performance (depending on how much further).

Have you replaced the TIM? You could do that, it may give you around 5*c or so drop in temps and there is no point putting on heatsinks on the metal heatsink plate covering the card since it will not make much of a difference.

Because his card is a non-reference MSI card and most of which (Twin Frozr/Hawk/Lightning) come with extra voltage control options. Those aren't available for reference cards or those of any other brand (with Afterburner).

That^, mine is reference, didnt know non-reference had extra voltage option xD

Raziel , repped.

First up , I assumed Erick was talking about an MSI card.. smile.gif
Anyway ...

The extra shaders are a 9% increase in raw core performance smile.gif Not going back , sir smile.gif
Sure I could hit 1GHz then .. but I like the extra shaders wink.gif

Blademasters are fans by cooler master with good static pressure levels ..
they're the same fans that come with the hyper 212+ ( hence the popularity) and are even used in the Vahalla redesign of the xbox 360

Product pages ..
92 MM
80MM

Checking out the 80 mm ,it'll make for a better fit ...

You have got to love those figures..

Esp the 4.23mm H2O air pressure..
and the 13-28dB noise levels..

But the problem - they're sleeve bearing,. but i don't mind replacing them every year.laugher.gif
I was wondering if putting the fans in as blowing AWAY from the card .. not into it .. would help ?? smile.gif I just feel that that it would allow for more rapid dissipation of heat.. I have a 220mm fan as exhaust on the side panel so this *may* help ??

Thanks!
PS : To tie them , I may have to chain tie zip ties across the whole heatsink .. as in one long closed loop tying the fan to the heatsink smile.gif

EDIT
: Will be changing the TIM once I find my Ceramique .. I know its lying here somewhere..
Was looking forward to getting this all done once I'd fix the fans on ..

Next question : What about the power ?? Can I source it off the main GFX PCB ?? Must I connect them to the Molex output ? The point of having PWM fans ... and I was wondering whether Simply Y-splitting the cables would work for both the fans ..

I would not change the custom fans(they can really disperse air), but rather design a new airduct which directs more airflow to the gpu from currently vacant vents.
Maybe casting a hand shaped toilet paper roll airduct with forced induction(jizz word) fan installation within its custom shape could double the air actually reaching the heatsinks.
I'm actually getting more feasible, the more I dream about this stuff.
