Would digg this fanless fan on X1000

[Christopher Follett]

Speaking of small fans, my A1XE had the small original fan on it for 5 years with no heat problems. It did overheat when I first got it, but it was not the CFM, it was that the fan was too close to the heatsink and the center of the fan did not allow air to be drawn toward the hot center of the heatsink.

To fix that airflow problem I took a fan off an old graphics card and cut the fan out leaving only the outside frame. Then, with longer screws put the new 'spacer' under the fan. I also cut a shim, aluminum foil, that would direct air further into the heatsink before going up the chimney and put that between the spacer and the heatsink. Problem solved.

I wonder if the cpu fan noise is amplified because the fan is so close to the heatsink, be interesting to lift it a little bit to see if it helps with the noise & cooling.

I didnt notice that much of a difference, when I was messing with a fan today on X1000.

I am shocked at how noisy the X1000 is. My quad core 6850 based pc is virtually silent.

Such a low power consuming system like the X1000 should be able to run much quieter.?
Noisiest fan in my X1000 is the one on the 4850.

You're blaming the X-1000 for that?

Well, the X1000 *is* shipped as a complete system... but I thought it shipped with a Radeon HD *4650*? (or was 4850 a typo?)

[ddni]

Yes I am blaming the X1000 complete system. I would like some OS based way of monitoring or controlling fan speeds. Maybe this is in the works?

Regarding the 4850 it is a choice on the second batch configurator.
Also included is:
5450
6570
6870

@ddni
It seems that the root of the problem (going by what was said above) is that your graphics card is one (of the few?) which doesn't set it's fan speed according to it's temperature. Either that or the graphics card is faulty.

Either way I suggest raising a ticket with AmigaKit, and see what they say...

The 7970 runs alot quieter than the 4980

[trevordick]

In my AmigaOS 4 & Linux tests I have tested around a dozen Radeon HD cards from the 4xxx, 5xxx, 6xxxx series and even one from the 7xxxx series

Unfortunately, the more powerful the card in any given Radeon HD series, the noiser the fan or fans (in some cases). I personally prefer cards with passive cooling (if possible). e.g. I have a nice Sapphire 5670 and Sapphire 7750 which are both passively cooled. Fortunately the A1-X1000 case does tend to reduce most of the fan noise.

I'm a fan of the A1-X1000 case and I never shut up about it. So there

Well the card is certainly not faulty.

Not all cards work the same, mine runs at full speed until it loads the software on my PC.
So if I dont have that software, then it would stay at full speed. Does that mean card is faulty?
