At least the over-hyped Noctua fans should be tested

Does it help to turn the mounting plate 90 degrees?

If I understood correctly you are only measuring the performance on open air with no back pressure. AFAIK the reality is different when the fan has to fight against the lower case pressure etc. Do you have any plans to test the fans with a case or with a heatsink to reflect real world performance? P...

I don't think they are overkill - at least if you overclock. A bigger/more efficient heatsink means that it can be used with less airflow. So they are definitely not overkill if you want silence.

Have you tried with lower NB voltage?

How much have you overvolted? (And what is the stock voltage?)

Well, that is quite a big reduction if you really measured the temps at identical conditions.

I think it is 100% BS.

Actually: underclocking -> reducing the clock speed of the processor (either by lowering FSB or lowering the multiplier) undervolting -> reducing the voltage of the processor Underclocking reduces the performance and heat dissipation. Undervolting reduces only the heat dissipation but might render t...

4 hours might not be enough if your ambient temp is not at max during that time. You should start the tests well before the room temp is at max. That is the best way to ensure your system works.

Ouch! Heyyyy...... Ok, sorry if I offeneded anybody :) The point is that IF you find a good deal on 939 system, go ahead. But the reasale value should be considered. Who knows if you wanted to upgrade a bit earlier than you initially thought. AM2/775 will be valuable then: you get new parts for the...

You can get a 6200 pci-e for $20 with mail in rebate. I'm not familiar with undervolting intel chips though. It depends on BIOS settings. And if you can't undervolt in BIOS, most likely you can undervolt with software? And if you can't undervolt at all, you can overclock and make that E6300 faster ...

And if you are considering X2 you really should consider Core 2 Duo. E6300 can be underclocked and undervolted if you want that. It will outperform 3800+ X2 in all cases (at least with stock speed) and probably consume less power in load.

You can also do this with Intel Thermal Analysis Tool (not available at Intel site?) http://www.xtremesystems.org/forums/showthread.php?t=115390 Also Speedfan will be supporting DTS (Digital Thermal Sensor) in a later relase. There is a DTS in both cores so TAT and CoreTemp use DTSs to get the tempe...

Also consider resale value. Buying 939 now would be a very stupid thing to do. AMD will drop the support completely after this year. Nobody wants to buy your old computer. AM2 and 775 will live long (2 years maybe) from now one and there will be buyers at least if you buy a mobo that supports Kentsf...

Actually the X-model is worse. It has lower MTBF figure than the normal version.

(I also think that it is an overkill. It produces more noise and the performance difference is quite small. And it is very expensive.)

I wouldn't get the Thermalright Ultra-120. The Scythe Ninja performs better a low airflow (which is what you'll want to keep the system quiet). I don't think this statement is valid. According to SPCR tests Ultra-120 was better than Ninja with Nexus@12V, Nexus@9V and Nexus@7V. When Nexus was at 5V ...

I think they do blow a bit more than my S-Flex 1200rpm, atleast it feels so on my hand, and soundwise they are about the same. So they are pretty good :-) I think your Scythes are at least as good as the Noctuas: http://www.au-ja.de/review-noctuanfs12-4.phtml http://www.au-ja.de/review-noctuanfs12-...

Yeah, but I'm pretty sure those differences are within the margin of error (0.8dB @ 4cm/90 degrees, 1C in CPU temp using some thin tower cooler on X6800). It's certainly not a much worse fan than the Scythe, and comes with an adapter to lower speeds. Yes, you are very correct. But for all practical...

Look at this review (link at Noctua site): http://www.au-ja.de/review-noctuanfs12-4.phtml http://www.au-ja.de/review-noctuanfs12-5.phtml As you can see, Scythe@1200rpm is quieter than Noctua@1288RPM and at the same time Scythe gives lower temperatures. What more you need to know? There is nothing sp...

Different motherboards are used in the HotHardware test. Only compare nVidia cards with other nVidia cards and ATi cards with other ATi cards. And they show the results in the same graph? That is just plain stupid. nVidia chipsets are very power hungry. Basically you can't make any conclusions on V...

Hmm, something is not right.

7900GTX consumes at most 89W (load). So basically the chart is telling that X1950 Pro consumes only 21W (68W less than 7900GTX)??? I can't believe that. Or then I can't read charts.

You never mentioned size or portability so its wide open :) Got me on that one :) The core2duo OC'ing doesnt benefit from h2o is ridiculous. overvolt a C2D and it will get very hot just like any CPU. Just look at the results. I really didn't make them up. I'm not saying that the temps would be same...

And please post the specs of Noctua fans - just for the record. Hint: look at the "extrapolated" noise figures Those must kick some serious ass

That is a normal low RPM fan. Nothing special, nothing that makes it better/worse than others. Just remember that faster fans make more noise and move more air. No magic involved. I'd buy a 1200rpm fan (like Nexus) and undervold it if needed.

I have no actual experience on watercooling (WC) but I have read quite a bit about it. I also wanted to try WC at one point but was convinced that it might not be better than AC at all. A few thoughts: 1. WC doesn't seem to have any overclocking advantage over aircooling (AC) when using Core 2 Duo p...

What these big tower heatsinks really need is a bolt-through mounting similar to the Asus Silent Square, which looks a good deal more solid than anything from Scythe or Thermalright... There is no evidence that even Infinity weights too much. I've read no problems with the weight - unless you move ...

The jury is still out regarding Ninja rev.B. It might be that rotating the mounting plate 90 degrees solves all problems:

Yeah, he told there is a beta available for testing. How is it looking so far?

Unfortunately, I’m not aware of any utilities that can control fan speeds based on the DTS readings. I’ve emailed Alfredo Milani-Comparetti of Speedfan fame about this, but I’m not clear from his initial reply what his position with regard to supporting the DTS is. As always, if there’s a f...
