Asus 7870 V2 Buzzz at 40degrees

[appileh]

Hello everyone!!

Well lets start! I bought a ASUS 7870 combined with my AMD llano overclocked to 3600MHZ. It is really a good graphic card,but i get a buzz when it is between 38 C and 41 C. When this temp drops from 38C I hear nothing,when it is increasing (above 41 C) i don't hear anything. Does anyone know what the problem is..

The problem is you're confronting a coil whine. Ghetto fix for that is put some black tape or any tape around it.

But, I would prefer to RMA it back.

 

[appileh]

Oke thanks!! I would like to RMA ,but i think they will replace it with a refurb card. And the buzzing sound is around 38 and 42 degree, so tape is better right?

 

[acerace]

Well, not for a long term though. It might melt sooner or later.

I suggest you RMA it if things go a lot worse.

 

[appileh]

Oke , I called the retailer(mycom) and ask if they could change my card for 7950 and it was ok!

 

[acerace]

Go for it you lucky b.....

 

[appileh]

Oke i changed it! And guess what? Same annoying sound. I think it is my 600W cheap Recom PSU

 

[acerace]

Oh dammit. The annoying sound is still there even when you not installing any graphics card?

 

[appileh]

Thanks mate for youre quick reply.

But the sound is coming from the graphic card when he is cooling from 42 to 38 degree..

Is there a cable or something leaning against the card in question?
The specific cooler fan frequency at those temperatures might invoke resonance in something, I suppose.

Oke guys i found the problem!! It is my PSU from Recom 600WATT.. It is buzzing around these temps of my graphic card.. What to do? Should i change it or leave it..

Damn i give a lot of money away for my pc ,but now my PSU is crap.. Damn ..

But it's really weird, I mean onyl between the 38 and 43 degrees the sound pop up.. Damn I changed my graphic card for it,for a bigger one and it was really hard to put the graphic card into my Midi Tower.. Here we go again..

 

[acerace]

Maybe the PSU cannot supply enough power to the graphics card, hence the coil whine. What is your budget for the PSU?

 

[appileh]

MY budget went to zero,but a power supply is important.. My budget is max 70/80 Euro..

My specs:

CPU: Amd llano 3850 3,4 GHZ (OC) with Coolermaster 412S (Midi tower modified)
GPU: ASUS 7950 TOP V2
RAM: Corsair 8 GB (1600 MHZ)
Motherboard: A75MA-P35 FM1
Drives: SSD Vertex 3-128 gb and HDD WD

This will do the job excellently http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049 Try looking if it's available in your country.

I bought a Corsair650 (80 % Gold). I returned the other power supply i changed it for this one Thanks Acerace for your support!! And it is working like a charm! Fingers crossed!

 

[acerace]

It will. If I remember correctly, the warranty of the Corsair PSU is 5 years. So, optimistically, it will work that long.

 

[appileh]

I hope so mate !! Corsair have a nice warranty system,hope that the PSU last long for 5 years
