From memory, my 58070 Vapor-X idles at around 1,050rpm at a 21% fan duty cycle according to GPU-Z, although I'm not at home to confirm this at the moment. (...) As for noise, my rig seems just a little noisier on idle (compared to with the 8800GTX with Zalman GV1000 at about 3.5-4V). I also haven't...

I've put this fan in my previously somewhat noisy Zalman 600W PSU in my P182. With rubber mounts, I don't hear it.

I'm based in the UK and my realistic budget is about £500/600 ($800-900) The minimum spec I would want is: Intel Core i5 750 2.66GHz CPU (or AMD equivalent) ATI HD 4670 1GB PCI Express Graphics Card 4GB 1333MHz DDR3 Ram 500GB HDD Plus the necessary components to quieten the machine i.e. cooler for...

I don't know if this would be what you're after, but Razer make some mice with infrared sensors instead of the usual optical lasers - I think it is the Death Adder and the Diamondback models from memory.

What is the best way to cover up open power supply hole, just tape? Actually, I got some modder's mesh and cut it so it fits in the PSU holding bracket on the Q07 and held it in place with some nuts and bolts. Looks a bit cleaner IMO and allows some venting. NSK3480 is probably my second choice. I ...

If you can stretch for the extra cost, why not go for a mini-ITX H55 motherboard and fit it into a Lian Li Q07? Zotac is currently selling a H55 mini-ITX motherboard, and Gigabyte is apparently coming out with one soon. Add a large tower heatsink of your choice and you'll only need one fan, on the C...

Interesting article - thanks for the review Lawrence & MikeC. Since the pump is run off a standard 3 pin fan header, would it be possible to do some tests with undervolting the pump? I vaguely recall one review site on the web that did this with a H50 when it first came out, but I can't find the rev...

The ATX motherboard specification is 305mm × 244mm (or approximately 12" x 10"). This would leave you at most 6" of depth. Hard drives and/or optical bay drives are typically positioned in front of the motherboard in most cases, which would add more than 6" to the depth of the case. Therefore, with...

I bought a blue LED Nexus to experiment with at some stage. I never actually mounted it in a case so I can't speak to any increased vibrations, but I did test it in free air. It seemed more prone to poor airflow and increased noise in a horizontal (blowing up) position than a normal Nexus fan. It ma...

As a more expensive alternative, consider the Scythe Kaze Server fan controller. I've installed one in my P182 and I really like its ability to control fan speeds in multiple types of ways based on temperature: - manual mode : dial in a fixed fan speed manually, no temperature-based variation - semi...

coolhand wrote:still hear some turbulance from the rear exhaust(Noctua 120mm at 385RPM)

Try cutting out the rear fan grill with some tin snips. This should reduce the turbulence noise.

If you need some form of fan guard to avoid potential finger injuries, try a simple wire fan guard.

My understanding of watercooling is admittedly limited, but isn't it more typical to mount radiators on the top / roof of the case above the motherboard (typically with a bottom mounted PSU)? The only rear-mounted radiators I have seen tend to be externally mounted using adapters to be connected to ...

For CPU temps at 4Ghz, I'm not 100% sure that one or two Nexus fans (even at 12V) will be able to cope. A 44C rise (over 20-21C) ambient with dual Nexus fans at 12V with a 3.6 GHz / 1.4V CPU might translate to temperatures a bit higher at 4Ghz. You might want a bit more headroom for the fans - somet...

I love my Q07 - I've done a little bit of modding to fit an undersize G31 mATX motherboard in there with an undervolted and underclocked E5200 and a HR-01+, with a PW200V + 60W brick providing the power. I've got a single Slipstream 800rpm fan at 5V (approx 400rpm I guess) on the HR-01+ which is ina...

GPU: Which of these 5870s? The Sapphire 5870 Vapor-X would be my choice. There is a thread about this card somewhere around the forums. I seem to have lucked out with my 5870 Vapor-X and got a card with a fan that idles at lower rpm than most. The model number listed at that site indicates that the...

Hope this Q isn't too off-topic, but why does Lian-Li use the removable PSU bracket? I see it on a lot of their cases, and never really got it. What benefit is it? Just so you can flip it 180 deg? Seems like an awfully complex solution to that problem (vs a few extra screw holes). I always assumed ...

SpeedFan should be able to monitor your HDD temperatures. If you are not getting temps for your HDDs, check if SMART is enabled in your BIOS. I'm curious about your airflow direction - is the side 120mm Noctua acting as an intake or exhaust (I am assuming the latter). Either way, you shouldn't need ...

Other than that, why would someone buy the Prolimatech Armageddon instead of the Prolimatech Megahalems? About the only other reason I could think of is because the Armageddon is compatible with 140mm fans, which could potentially provide higher airflow than a 120mm fan at similar voltages. On that...

The FT-02B looks like a much better prospect for quiet cooling than the Corsair case. I don't see much intakes on the Corsair case, and what intake grills there seem to be appear to involve pushing air through HDD cages. The FT-02B has pretty unobstructed internal airflow. All I would do is remove t...

The Nexus Real Silent 80mm fan is another option, depending on how you orient the case. If the mobo is sitting flat so the fan is on the side, this is fine. If the case will be standing on its side with the fan on the top, I'd go with the Noctua.

For fan speed, you need some cable adapters that set fan voltage lower than the default 12V, or if your motherboard is compatible - software called SpeedFan. Your motherboard might also have some software that works. Do what ces suggested and manually stop or disconnect some of your fans to see what...

Thermalright HR-01+ or Scythe Ninja.

FWIW, I don't understand the need to go completely passive. A quality fan undervolted to low rpm (<500) is effectively inaudible and will make a difference in temperatures of your components.

I notice you didn't mention whether you had a passive PSU or not.

FWIW, the 500Gb 2.5inch drive in my Seagate FreeAgent USB2 external HDD is pretty quiet. I assume it is a 2 platter Seagate Momentus 5400.x HDD in there.

The F3 you mentioned is another option (assuming you get the 5,400rpm EcoGreen version), but I don't have any experience with that drive.

Unfortunately, turns out the Thermalright and Noctua are too high to fit in this compact box :-/ I'll see if find another solution. Thank you. Have you considered one of the Zalman passive Northbridge coolers ? Ive used a ZM-NB47J on the Southbridge of a G31 board with reasonable results. They are ...

If what you are trying to accomplish is a switch that determines whether a second HDD (in addition to your primary linux hdd) is allowed to turn on at boot, I've done something similar before. I did this with a SATA drive before switching to an external USB HDD cage with an on/off switch. I used a f...

Running them both at 5 volts, is your assessment that the slipstream might be generating substantially more CFM than the GT, perhaps double? Or that the air current for the two fans at 5v is basically the same? Honestly, I haven't done a side by side comparison. I bought the GT to try it, found I l...

Admittedly the above is not conclusive, but it does seem to indicate that in free air the Slipstream in comparision to the GT, is the superior fan delivering substantially more CFM at the same noise level. I would submit that under high impedance, the roles would reverse. Well, as I indicated, the ...

Not happy with the added noise of the Zalman fan when I don't have the headphones on though, so looking for either a replacement cooler (Scythe Mushai probably) or a replacement card. What voltage are you running the GV1000's fan on? I had a GV1000 mounted on my old 8800GTX, and the fan started at ...
