Is there a fault with my HD7870?

Hi,

I have an MSI HD7870 Black Knight Edition that I believe may have developed a fault; it has become exceptionally noisey of late, due to extremely high rpm speeds, even at low load. I have been using GPU-Z to track its fan speed, temperature and fan rpm, and have noticed that when idling the fan runs at 30% and ~1200rpm. When gaming, both the AMD Catalyst Control Centre and GPU-Z report that the fans are running at 40% load, and temperatures are averaging 57'C (max temperature was 69'C so still well below a 'high' temperature for a GPU, Im sure you'll agree) - the problem is, the fans are at ~4400rpm. There are occasions where my fan has hit 60%, whereby I can literally hear my PC from 2 storeys down.

I am unsure as to whether the following is part of the issue or just how the cards are set, but at a 0% load the fans are still running at 30% and ~1200rpm - I would have though, and have seen in other cards of mine, that at idle, the fans drop to much lower rpms.

Would anyone be able to advise as to whether this is a fault, or merely the way these particular cards are set up?

Kind regards,
Cookeh
 
Download MSI Afterburner and set a fan profile or so in that... i use it.. great little piece of software

My 7870 had a fan problem, so i just bought an aftermarket cooler and fine now

Temps are fine from what you have told me

Checked the fan(s) for a broken fan fin at all?
 
I've set a fan profile now, but my concern is that it is a fan controller issue - so altering temp vs fan load wont necessarily have any impact at all. I'll update this thread when I can better comment on the result. Thanks for the idea though, hopefully it will work!

There are no broken fins, no damage to the housing either. I dont suppose you would be able to tell me what rpm your fans run at at 30 and 40% load? I know this is pushing it a bit, but do you perchance recall what it was before you changed the cooler?
 
each card is different... different manufacturer, different model, different fan types lol... it all depends on what type of card you have
 
I had a loan of a 7870 to test out for a mate. It ran games great but compared to my 7970 it sounded like a jet engine! I enjoyed the peaceful tranquility after giving it back :p
 
as stated the 7870 is a great gpu.. about 3% slower than a 270x.. soi nothing in it really.

my VTX3D 7870 sounded like a jet engine when i got it, hence the reason i put a gelid icy vision on it instead...

to be fair, the black knight edition seems to be the cheaper alternative to the twin frozr... which is usually quiet and its fans are designed to be... maybe it being a cheaper card, it doesn't have silenter fans on it
 
That could be it, and I could just be noticing the noise more and more of late. The only reason I asked about your fan rpms is to perhaps try and establish if the rpms mine are running at are approximately correct or way off (potentially indicating a fan controller issue).

With regards to the MSI Afterburner Fan Profile, it made no difference to noise of fan rpms, but it did allow me to stop the fan load hitting 40% as quickly as normal, so the card is quieter for that bit longer.
 
go poundland and get an air duster... your from nottingham... one next to dog and partridge pub in town, opposite boots has plenty in, i use them... they are good
 
Cleaned it out a few weeks back, whole PC gets an airblasting every couple of months. I will give it a go though, noise is really getting on my nerves now!

If the MSI is using sleeve bearing fans,it is quite likely they have started to wear out,so have started to get noisier as time progresses.

Edit!!

I just saw this thread:

Same problem as the OP is having. Appears to be a faulty diode.

That is the exact issue, seems there is another thread on it too that is indicative of the diode being the only solution. It also seems to indicate that an RMA through MSI (OcUK is not an option as the card is itself an RMA replacement) may not come to any fruition.

4400rpm sounds very high imo. I've not seen a fan in my pc go even close to that. And you say that is not even at 100%?

Yes, 4400rpm is the claimed rpm by GPU-Z and Afterburner - both reading 40% fan load. Fan is silent at 30% load (1200rpm), but the second the temp ramps it up to 40% load it hits 4400rpm.

That is a little concerning, sounds like something to do with the fan controller on the card. An extra 10% shouldn't go upto 4400rpm and sound like a jet.
 
That is precisely my point and the reason I started the thread ;) :p CAT-THE-FIFTHs edit seemed to match my issue precisely, meaning I either have to lop a diode off of the card, or try to get an RMA with MSI directly - who then may not actually find a fault with the card.
