Re: Going to mod variable resistors onto fans. What resistan

I just ordered 2x Yate D12SL's and when they get here I'm going to mount a variable resistor onto the fan body and cut and solder the wires onto the resistor to be able to tune each fan individually for best results and have that change permanent for each fan. Any suggestions on what kind of resist...

Re: NVidia GPU always runs full speed when using multi scree

This is normal and it's this way to avoid tearing issues between the two monitors (according to evga support). My impression was that ATI cards capable of lowering clock speed also do the same thing(?) On my card, running dual monitor config uses up an additional ~60W. One solution would be to use t...

Re: Black-Ice SR-1 120 on a GTX580

How about a little pros/cons chart at the end ? Good suggestion, I have added it. Do you think a push/pull fan configuration would improve temps at lower fan speeds ? I did try this for some combos and only saw approximately 1C improvement. From the pics, I understand that the radiator is fed fresh...

Black-Ice SR-1 120 on a GTX580

Most reviews/articles I have seen of water cooling systems focus on achieving lowest possible delta-T from ambient, with 10C or below as the golden target and anything above 15C is an “overloaded” water cooling system. This review is different because I am going to focus on whether a single 120x120 ...

Re: Thermalright Shaman on GTX570

Finally someone tried and reported back :o. What did you use as load the card? Did you connect the thermalright fan directly to the video card header? Last, if you don't mind (and feel it's safe), can you run an older version of furmark (like 1.6.x) and report temps. Thx.

Re: GTX 570 / GTX 580 / HD 6970 quiet on air (water maybe) ?

Hmm... I wouldn't expect it to be that bad just from looking at the measured noise levels. It's not that bad at idle, unless your goal is silence in a quiet environment, idle noise can probably be ignored by most. On load it's still not as noisy as my hair dryer on low (I have a noisy hair dryer :l...

Re: GTX 570 / GTX 580 / HD 6970 quiet on air (water maybe) ?

Here's another 580 review that mentions (the lack of) fan noise. Honestly, I think someone finally figured out that noisy stock coolers are a bad thing, and did something proper about it. It may be quieter than before but it's neither quiet nor silent. At idle, fan is spinning at ~1400 RPM and I ca...

It's running on the GPU--a GTX580, it will do around 15.5k pts/day if I don't slow down the clock. I'm probably the only one doing that to this card :mrgreen: .

Hi, I have a P182 case and use Enermax Modu82+ PSU. I am very happy with the PSU.

I have four drives in the lower bay so I kept the fan in the middle, otherwise I don't think it's necessary specially if you're not going to place any HD's in that section.

I have no experience with the graphics card but your combo looks good. The only other thing I would consider is to replace the two case fans, the one on top and the one on the back with something else.

A fan in sandwich configuration will have a harder time moving air through the grills since air has to pass through two restricted areas (intake and outflow). In order to develop equivalent air velocity as a fan only pushing through resistance, it has to spin faster translating into more noise.
