Yes, the fan speed signal is in the 3rd wire and was reported fine by the motherboard. Regards, Seb So the idea would be to make an adapter in order to slow down the fan of a Sapphire 4870 Vapor-X video card http://xtreview.com/images/radeon%20HD%204870%20vaporc%20pic%2003.jpg http://www.pctuner.ne...

Hi, in this thread I talk about my experaince of adding a fanmate in the loop with a PWM fan to effectively move the working range. I.E. change a 1300-2600rpm fan to a 1000-2000rpm fan. I think PWM fans can vary in how they respond to voltage changes, some will be very sensitive, other less so and ...

What SebRad said, correctly describes what I want to accomplish.

"I.E. change a 1300-2600rpm (PWM) fan to a 1000-2000rpm fan."

Is there a way to slow down a PWM fan at "hardware" level?

Well... with a 3-pin fan we can undervolt it using resistors etc. is there a way to "slow down" a PWM-controlled fan adding something in the middle of the cable?

... what about this video card? I'm very wavered between GTX 260 and this HD 4870 1 GB Vapor-X, it's a shame SPCR didn't review it

I do understand what you're saying, they measured the whole system and not only the card so in a relative point of view the vapor-X seems to be fairly quiet. You need a working PC to make it work :D Yeah... maybe they could use a fanless PC instead. You italians are at times so strange no wonder yo...

Another review: http://www.overclockersclub.com/reviews ... 0_vapor_x/

Well here certainly is a contradiction, when someone says quietest it can pretty safely be assumed that it is under 20dB(A). Those italians measured nearly 55dB which is ear-raping and not quiet! I think they tested the whole system with the video card inside. ;) So I think you should look at it in...

Well then it completely is a bad measurement. Do they have an old Pentium 4 probably overclocked to 5GHz which needs that f**king loud 5000RPM fan?

NO WAY a card is going up 55dB! What, did they measure 1mm away?

I think they tested the whole system with the video card inside.

VelociRaptors are more expensive and still noisier by specs, so your remarks are plaing wrong, again. Well, obviously. They're completely different kinds of HDD's.

Yeah it is but you are not comparing apples-to-apples. Moreover, there are no cases where a 3-platter version of a disk is quieter than a 2-platter version of the same disk series. Of course a 2-platter Maxtor could be noisier than a 3-platter Western Digital, but this is not what we are talking ab...

The VelociRaptor is also not in direct competition with the Blue or Black. But seriously, "Buy the new WD Black, it has a marginal performance boost over the Blue with only an increase in heat and noise!" is not a very easy sales pitch.
