Would a good exhaust fan have different characteristics from an intake fan? Yes, but exactly what characteristics you want from the exhaust fan depends on the total setup. * If the exhaust fan is to provide all airflow, with no intake fans present, then it should be (relatively) high flow. * If you...

Do not get the Silent Wings 3 as a case fan if there's going to be a dust filter directly in front of them. The SW3 is a great fan in open air and as a heatsink fan, but placed against a filter it creates a lot of turbulence. Its measured dBA may still be low but the quality of the noise is really j...

Another thing to consider is idle noise. For me this is way more important than noise at full load, since the system idle most of the time and at load other things like maybe the graphics card fans will also get louder making the CPU fan less of a main concern. The fan can play a bigger role than t...

The 212 EVO is pretty good. You don't need more cooling than it provides with the fan running quietly. it is the sound im worried about. Dark Rock Slim is whisper quiet at normal loads. Depending on where you live it may not cost a lot more than the 212 EVO. But if the price difference is too much ...

But wouldn't an exhaust fan need enough static pressure to blow out through the back grill? I guess some, but aren't exhaust grills typically quite open? Some are, some aren't. A grill type would be more open than say a honeycomb type. Still, I would imagine some fans would be better than others at...

You can also see the Noctua vs. Arctic, Nidec - Ultimate 120mm Fan Re-match! , which favors noctua, and compares lots of the same fans as TBG tests. This test has the same flaw as the Hardware Scientist test. They only test the fan noise levels in free air with no mesh filter or any other obstructi...

I picked up a Noiseblocker fan recently at a big sale. I haven't got around to installing it yet. Reading the reviews on it talking about how it channels the air flow instead of spreading the air flow out made me think about how a good intake fan might differ from a good exhaust fan. Would a good e...

beQuiet! Dark Rock Slim has worked well with my 3600 in Fractal R6. Silent or very quiet even under load and not nearly as expensive as the heavier beQuiet! or Noctua coolers.

Has anyone bought these fans? They seemed to sound and perform a lot better than Noctua P12-redux in this Tech Buyer's Guru test. However I haven't seen literally anyone else reviewing these fans. Most other fan reviewers also don't test fans against mesh filters, which really makes a difference for...

In the Hardware Scientist test the case fans are tested essentially in free air as they are set up as exhaust fans. That means there's no filter or any other obstruction in front of the fans. The results are thus invalid for an actual case intake fan scenario. The Silent Wings 3 for instance is horr...

I would caution against Silent Wings 3 in general. I have the Fractal R6 and I was in the exact same situation as you. I got two Silent Wings 3 High-Speed fans to replace the Fractal fans... and the result was terrible. The SW3 produces a lot of turbulence when it's placed against the intake filter ...

The Asus fan turned out to be defective, and I received a replacement Asus DirectCU 5850 today. With the high-pitched rattling of the defective fan gone, and the 120mm case fans easily drowning the new GPU cooler fan at idle, the system as a whole is now very quiet. It's not totally silent and you c...

Turns out the Asus DirectCU 5850 I had issues with had a defective fan. I received a new one today, and the improvement is significant, especially at low rpm fan speeds. Whereas the old one used to have this whiny, rattling sound and was constantly audible even at the lowest rpm permitted by CCC (20...

How is the idle noise? If it's audible, what are the noise characteristics like (high pitch, rattle, smooth)?

Does anyone on SPCR own either of the Direct-CU versions of Radeon HD5850 by Asus? What kind of noise levels are you having on the cards, and specifically what type of sound is the card's cooler making at idle speeds and under load? I bought the card myself after reading numerous reviews of how sile...

Let me know how that i5-750 overclocking goes, especially what the temps are before and after.

Quick question: SPCR's review mentions a fairly audible clicking from the stock fans, is it true? Worth replacing them? Or did they just get bad samples? It's audible if you stick your head closer than 10cm from the vents, but indistinguishable from any further than that. At least on my system, whi...

A big factor with the temps you're seeing with my build is the HD5850, which has an exceptional thermal performance compared to past generations of GPUs. I've never owned the 8800GTX, but from what I've read you should be fine if the load temps don't exceed 85ºC. Higher operating temps have been re...

That's truly excellent performance! I'd be more than happy with that. My GPU is currently at 65c while idling with no sides on the case. :) Goes up to scary temps when gaming. Old skool 8000GTX furnace. I was thinking of putting the Fractal exhaust in the front, my 1200 rpm quiet fan as rear exhaus...

And I must say I'm truly happy with the thermal performance of this case.

Its suitability for high-performance components and even overclocking is not what I expected from a silent PC case. No need to get loud over OC.

Very nice setup - and like how tidy the install is cable wise. I've tried to keep mine as tidy as possible but I think you've managed it even better. So you have two intakes at the front (the fans that came with the R2) and a bottom intake but no exhaust? Thank you. That is correct. I'm trying to d...

Update: Dust-free with positive pressure Since the removal of the case exhaust fan and the upping of the total CFM of the intake fans, the system has been effectively dust free. Normally, even during a relatively short observation period such as this, the case would have accumulated a noticeable (n...

Bought mine in mid-April. There's definitely room for improvements in any eventual future revisions of the case, but most of those are minor issues by themselves. By far the biggest headache I had was with the P55-incompatible back plate opening and the slight I/O panel mismatch, but neither caused ...

And what would be a recommended aftermarket cooler for the 5850? The Vapor-X cooler I take it is not available separately?

Does anyone else have experiences with the Asus Direct-CU HD5850? It comes with a proprietary Asus cooler that's supposed to be quieter than the reference cooler, but mine has a slight but clearly audible rattle to it. The fan isn't otherwise audible at idle speeds, but the constant rattling sound o...

Update: More efficient cooling After a little experimenting with the case fan setup, I ended up changing the original fan positioning by removing the rear exhaust fan altogether and moving the more powerful 120mm Noctua fan to the bottom of the case, replacing the slightly quieter but lower-rpm 120...

Haven't been very happy with the Asus Direct-CU HD5850. The cooler is effective and the fan runs at a comfortably low rpm, so the usual GPU cooler turbine-like noise is not there. However, the fan has a very distinct rattling sound at anything below 70% fan speed (and then the fan is loud). It's not...

Got my new desktop up and running yesterday, and thought I'd share some first impressions as this forum has been a crucial source of information and support for my two silent-PC builds so far. The system is an i5-750 backed up by Asus Direct-CU HD5850 and 4GB of Corsair Dominator DDR3 on an Asus P7P...
