For static pressure the rule of thumb is that the thicker the better.
With the same free flow rating the noise (at free flow) will be higher though.

...greetings guys...my first post in Silentpreview so be kind huh? I'll try... ;) 1) Pumps ARE NOISY ... but what about centifugals ? Centrifugal pumps are what's generally used. Even those can be considered noisy if they're not perfectly balanced (which they're not). Often they're less noisy than ...

I use medical grade compressed air (available from the wall sockets at my workplace in a hospital, we use it to drive power tools as well). With fans I mostly hold them still while blowing at them, in order not to overstress the bearings. I do it rarely though, since the intake filters on my compute...

... Otherwise, you're dealing with a situation where all that is perceived is the past, which puts its possibility of having a manifest existence now at the same level as that which exists only in memory. That's crazy. I have absolutely no problem with this. 1. Signal transmission takes time. 2. Pe...

The specific case related to is one batch of laptop GPUs.
More troublesome is that some large laptop manufacturers (Dell and HP) that installed these GPUs do their best to avoid replacements.

Great review, with all applicable aspects covered and considered! (Except for use with AM2+ mobo. (Added after reading Bottom's comment.)) One thought though. How do you define "game [mother] board"? I just did a quick survey of the Swedish market, and the mobo used in your review is the cheapest AM...

The Extech 407738 you mentioned seems decent, ... Is an accuracy of +-1.4dB considered "decent"? It's poor enough to provide wide margins of error when computing the difference between two sounds <5dB apart. (For example calculating the contribution from source X on top of the background noise.)

Dough, you most probably won't need any more fans, and might even consider removing one of the already installed (blocking the place where it is mounted). The PSU fan will take care of all required cooling in the lower chamber, and provided you use the stock cooler on the graphics card, that will wo...

Antec P183, @£10 extra, is a generally better case that you might want to consider.

However, this review lacks any noise testing or even a single reference comment about noise, ... From the reviewer himself: I wasn't able to test the sound levels objectively (no DB meter), but I can give you my subjective opinion. I used an Antec P180B for about a year and enjoyed the low noise le...

Sites like this should not be trusted when it comes to quiet operation. No, but they're good enough for clueless newbies ...

Is this supposed to be math? how can you subtract the BG noise when you dont even know how it adds up, what frequencies contibuted to these mesurments, and what "sensor" they used. I know the background noise level and assume that the microphone is stationary throughout the tests. That's all it tak...

The 35W TDP seems quite low for this box, considering the size of its heatsinks. It's not that low if you also consider that it is to be dissipated at 50C room temperature! Given that a HDD reaches 50C when the ambient is 21C, what would happen if the room temperature went up another 25+ degrees? /...

I wonder about the noise and efficiency profiles for the less powerful siblings...
Which one does best at 30W, 100W and 300W draw?

Cheers
Olle

80W max seems pretty low compared to the fast cards.
To me it's the idle draw that defines thermal and power performance. It doesn't really matter if it draws 50 or 250W on full pull, as long as it's less than 10W on idle.

I've never had any problem with that. A few concentrated blows with compressed air does the trick nicely.

I wonder if pouring like 180 degree water or such would dissolve them. Possibly, and it would most probably kill the pump in the process (unless it's removed first)! Pumps are designed for water temperatures <35C, and should preferably only be exposed to water temps cooler than that. Source: Aquatu...

I’m a bit sceptic about using diamond dust in a TIM, at least when it comes to the expectations proclaimed. Diamond is a very good thermal conductor (2.5 to 12.5 times that of silver, depending on exact composition) because of its crystalline properties where heat is easily transferred between the...

It is much easier to dissipate a specific amount of heat at a single location, because that location will get hotter which helps removing the heat. If you make the dissipating area small enough, bla...

I'd like to chip in some advice on how to best measure the noise in a cheap manner. Provisions for making it in any way useful: 1. You have access to an audiometer (somewhat calibrated) with a floor at or below the background noise. 2. The computer is clearly audible above the background noise. How ...

I think Xbitlabs test is a bit off the mark, because of their system setup.

To make the test worthwh...

Wonder if you can replace the door with one from a P182. My question too. I sent it to Antec's EU support a while back. They couldn't give me a straight answer since they hadn't actually seen one yet, but agreed with me that it seems like a plausible possibility. (I'd rather use the brushed alu doo...

For extremely low system use I'd recommend Vipre , but only if you don't encounter malware very often. I recently fixed a friend's computer who's PSU was broken.
