Fans stuck on my 7950
-
Hello there thanks for answering, well let me see. Yup Sapphire Vapors.
-
Have you tried putting something on the fans bearings such as grease or oil or lubricant?
Although it may be too late if the fan has ceased.
-
Well actually… the contact cleaner helped a lot, then got some WD-40 on them. Will let them rest a while before testing.
-
Yeah… Sapphire… Hate em… Have had 10-15 Sapphire cards dieing because of this!
Baisclly the reason as far as i have found out is that over time the fan gets alot unbalanced (seems those cards dont like to be stacked sideways, that the fan rely on gravity).
You will notice the fan spin more and more out of control, until it puts such amount of strain on the motor that it will burn out.
Heres one of my Sapphire 280X OC cards getting close to doomesday…

Sapphire Toxic though seems good ;D

Good, because I’m about to buy a crap load of 270x Toxics…

Would rather have an look at Nvidia 750ti at this point in time ;D

If I go that low on hash rate I may as well buy gridseeds… Check out Zuesminer Professional, its giving me wet dreams…

With gridseed you can mine scrypt, thats it.
Kinda boring if all the major coins use an new modded scrypt (better for some reason, might happen). What are you gonna use your gridseed for then? paperweight?
At least with GPUs you can retarget other algos, or sell em down the road ;D

It’s a bit tricky with the 7950 and 7970 when the cooling breaks since the options for after market cooling is almost slim to zero.
However, the Prolimatech MK-26 actually works like a charm! Running it on my asus 7970 DCII since the original fan went awol the same way as described here.
I’m running this bad boy package:

Keeps the temp about 10 degrees celsius lower than asus DCII cooling :)

Sven I’m so glad you are around to give advice, you may have just saved me and my investors a $50k mistake. So what’s the deal with the 750ti? My local IT supplier is about to get 50 of these in stock:

Same deal as ATI cards, can fit 6 on a mobo with risers just use CudaMiner instead?

Whoa… those are charming, but pretty expensive also :-(

Those 750tis, someone on another Forum did a comparison of the PCB layout between the different manufacturers. From what I can remember, he suggested the EVGA might not be ideal for 24/7 mining, something about ironchokes and single phase??? Same guy praised the ASUS, but others later on in the thread claim they are less clockable.
EVGA do have a good warranty though.

I’ve experienced the same with the ATI cards. The Asus 270x has a glass jaw where the Sapphire 270x goes hard…
-
I’m curious as to why the ASUS won’t clock though. It’s arguably the better built card.

It’s loads quieter at comparable fan speeds, I wish they would as well…

Asus at least for 280X seems to be set really high in voltage, and have good overclocking headroom, for someone trying to control the power handling however…
That being said, at least with Asus you dont get “reference” power phases, which kinda sucks (at least for AMD), i have melted 4x Gigabyte 7970 OC and i know someone that has melted 12 of em, same place that gets broken on all the cards.
I would however say that i actually pr today prefer the sapphire toxic versions.
As to 750ti i have no idea… :) Still contemplating about building an seccond park with nvidias…
Im thinking EVGA however, just got an feeling. with no hard proof to back it up ;D

I would however go for the single fan version… Why dual fan? dont overclock, get 250-260khash with low heat, allmost no noice, and allmost no power consumption.
Reviews have shown that for scrypt mining at least, your looking at quite the accelleration in regards to power usage 250khash vs 280khash, at 250khash the card use 38w!, with 280, your looking at 65watt! Thats not much
but think cooler operation, less stress on card, longer lifespan and so on.
Also out of experience my 7970 rigs back in the day one quad 7970 rig (gigabyte triple fan design thingy), the difference in poweruse total on the rig varied from 1350w to 1100w. depending on current fan speed (1350 at 85% speed).
Now if you add that to the mix and looking at its supposed to be LOOOOW consumption, adding an extra fan on it… Which isnt needed given that the reviews states around 56degrees running scrypt.
Just my 5 cent ^-^
Edit:
Just realised that my writing was a bit messy now, tired and sleepy… let me know if it sounds gibberish and ill rephrase.
