IMHO, i think people who have reported problems with running fans at 7V, have probably gone wrong somewhere else and blamed it on the 7V fan mod - either that or jus got the mod wrong :roll: Regarding B) try www.fanbus.com or www.7volts.com Jus go for a panaflo instead of papst, the difference isnt ...

You're right, you dont see it much - pretty much its only Alpha HSs which perform better with the fan sucking air off it, (because of the shroud they use?). Also if you experiment you will see that turbulence noise is much greater when there is an obstacle on the input side of the fan. Just try it b...

Yep, its quite easy too! Prolly easiest to point to this [H]ard guide. You need to look half way down the page, where it has a coupla big pics of ATX mobo connectors

Have you tried unpluging the computer from the amp? Is the static still there? Can you give more details of your speaker setup pls?

Also how loud are we talking here? If music is normal level is this static clearly audible? or is it only if no signal is being played?

Think you misunderstood somewhere... I think the thermal resistance you are talking about is how they measure heatsink performance. Its measured in K/W (Kelvins per Watt - kelvins same as degrees celcius). It measures the rise in heat in your heatsink for each Watt off thermal energy put into it. Ie...

By the way my desk is of a very solid nature, very heavy in weight. I lifted the computer up as suggest by ChiefWeasel and I can't notice a difference in the noise level. Ah ok, my desk is just a chipboard ikea job, and even thou my computer doesnt feel like it is vibrating there was an audible dif...

Theres a couple here and here. But this is probably the best value... only £9.

You will definetley get better performance from 2x80s rather than 1x92. For example, with L1a's:

80mm = 21dB - 24CFM
92mm = 27dB - 43CFM

2x80mm = 24dB - 48CFM - much better stats than 1x92mm

If its on your desk then you will probably benefit by putting the whole thing on a soft mat of some kind. Try lifting the computer of the desk and see if it is any quieter, if so then try putting it on a mouse mat or a folded towel or something.

Also it says it doesnt have a fan monitoring wire, so does that mean the fan spins at full 12v all the time? Nah, jus means you cant monitor the RPM via a motherboard fan connector. The heatsinks in that PSU dont appear to be very good - heatsinks in my Q-Tech psu are much larger... Other than that...

I think you might find that it is your graphics card causing the whine - i used to have this problem too... There was an in depth thread about this a while back, not having any luck finding it tho...

Nope, hehe tho i agree with Rusty too

To be honest tho, dont think i really need anything anyway Mine is silent enough so i cant hear it at night, the only thing i need is a Matrox GFx card.

I've been thinking that a PSU shpould come with a Li-ion battery that it charges up for the first few mins, then shuts itself down before it gets too hot and then back on when the cell is almost drained, having had time to cool down again. Charging batteries is far from efficient, and would create ...

Yeah, it is a good idea. The trouble is how many different setups are there? If you think about how many different cases there are, and then mobos can have the CPU in different positions, and there are different height heatsinks, it makes it very difficult to manufacture something that will work pro...

Do you mean carpet underlay? Im using carpet underlay on both sides of my case. I also have a layer of dynamat type mass damping under the underlay. The sides are now very heavy! Wish i had a digi camera cos it looks pretty good :) It was a while ago i did it but i think it did make a difference, by...

I wouldnt be too hard to rig up something on the inside of the case would it? Im not sure what the requirements are for a faraday cage to work properly, but i think MikeC mentions it in his BreadBox PC article maybe... Maybe use some tinfoil, or metal grill fixed to the inside of the wood. Could als...

If you get the Cudas then you wont need Smartdrives. Decoupling using elastic is all that is needed, and will save you about £70 (~100Euros?).

What spec is the rest of your PC? Are you sure you need water cooling?

This isnt a good idea because fridges are designed to cool items which do NOT produce heat. Ie it normally cools them down, then relies on the insulation to keep them cool. But, if something in the fridge is actually continuously producing heat, the fridge's compressor will be running continuously c...

I heard the hole is to let out gasses released as the thermal compound inbetween the core and the Heat Spreader cured. Its fine to cover it with the HS, i did pretty much the same as WMPcTBDS regarding ASIII.

Nice! That HS look pretty bashed up tho! hehe. Funnily enough, im using a CPU cooler on my geforce 256 as well. Im using a golden orb tho! Im using a 80mm fan as well tho, not the stock Gorb fan... Edit: Just found a pic, but its from my old computer, when i was using the stock fan on the gorb - eve...

I suspect you will need to do more than just a new case and PSU? What CPU hs, gfx card, HDs, case fans do you have?

As for case and PSU, i would recommend an Antec 1040 (same as chieftec dragon) and Nexus PSU.

Ive got mine in the cupboard next to me, and i would urge you to get the highest quality video cable you can get , eg. Belkin. Dont bother trying a cheaper one because it will just be a waste of money - i speak from experience hehe :roll: But yeah, its great! absolute silence is surreal! PS you'll p...

Maybe look into some kind of duct, to duct cool outside air, straight to the PSU intake, like Leo did here? Though you'd prolly need a separate system exhaust fan if you do this...

Rusty, do you have a variable fan speed controller you can use to control the voltage to the fan? If so, try supplying it with a voltage just below the startup voltage, i think you'll find it will click like crazy! Im pretty sure this clicking is definetly louder than when it is at 12V.

I also found that the clicking is louder when the fans are undervolted, but like i said before, the clicking seems to have disappeared now... very strange...

Oh no, not another AMD/Intel battle :( Anyway, so zambaretzu isnt mislead by Gandalf's posts, i feel the need to post a link to a coupla pages which show a wide range of benchmarks to fairly compare the two processors courtesy of [H]ardOCP: Business Benchies Game Benchies Gandalf, you need to realis...

Jus had a listen, and i cant hear any clicking at all, and i have 4 papsts in my comp. They are all undervolted between 5 and 9V. They definetley used to click, but even when new the clicking wasnt really audible with the rest of the computer fired up. They are fine i think, altho i really dont thin...

Yep, WMPTBDS is right, you will need some airflow in there. Panaflo L1as at 5 or 7V are very quiet anyway, in a dorm environment you would probably never hear them. 1 on the CPU, 1 as an exhaust, maybe 2. You wont need to grommet the drive mounts if you use a NoVibes... Underclocking would certainly...

Ill have another listen tonite, but i think if its inside your case and you're a metre away you wouldnt hear the clicking.

Thanks.

The one at heatsink guide varies the voltage continuously from startup to max voltage.
