I tested mine the same way; it ran at 1400 rpm @12v rather than the 1300 rpm it is rated at. Same conclusions as you.

I think that your tests eliminate the PSU. What I would do next is this. Disconnect any drives, - hard, optical etc - both power and data leads. So that all you have is the motherboard, cpu, memory and video card. Remove one pair of your four RAM sticks. Try to start. If this doesn't work, then remo...

I'm sure about the PSU and video card as I my PC died recently and I had the parts tested to diagnose what turned out to be a fried motherboard. Given that history I would be extremely suspicious about the PSU. It may be that it passes a basic diagnostic test, but it does not necessarily mean that ...

You don't have to turn off the supply to a fan to stop it turning, dropping the voltage to around 1V/2V can do it. Some fan controllers use this technique, for example http://www.bcchardware.com/index.php?op ... mitstart=1.

Yes I have bought these. Partly it's because my local PC hardware store stocks them see http://www.scan.co.uk/Product.aspx?WebProductId=782928 . I think a lot of people fit them just because they look better. (But the back of the case is not on view??). There are one or two reports that users with h...

I must admit that having fitted 2 Noctua CPU coolers to date I have always replaced the Noctua fan with a PWM model. This is partly because I prefer the logic of PWM, i.e. low fan revs at idle increasing with the load and also because it plain just works. The choice of PWM fan is partly dictated by ...

It seems to me that you are putting a high-performance, hot running Core i7 system into a smallish case with virtually no airflow. You are also going to buy 1600 memory which suggests you are planning to overclock which has implications in terms of additional power consumption and heat production. I...

I don't get a 404, I get http://www.corsair.com/products/dominator/default.aspx which seems to be about Corsair memory not PSUs.

Basically, the Core i5 870 seems to match i7 920 in performance, with the i5 750 lagging behind to varying degrees. Core i5/Core i7 is not determined solely by socket 1156 or 1366. So the 870 is a Core i7 CPU, along with the 860 and the 860s. The 750 and 750s will be Core i5. Core i7 on the LGA 115...

Why not consider using the Akasa AK-CB002 PWM splitter cable. This has the advantage of not drawing fan power through the motherboard headers, and any motherboard with a PWM CPU socket will be sufficient. See (in the UK) for example http://www.dabs.com/products/Akasa-PWM-splitter---smart-fan-cable-5...

Some UK suppliers are now advertising the 45w Sempron 140, such as http://www.scan.co.uk/Products/AMD-Semp ... 45W-Retail.

CUDA can make a big difference because it takes so much load off the CPU e.g. this comment by a CUDA/CoreAVC user "....On 1080p mkv content, I would pretty much be at 100% CPU usage all the time, with heavy stuttering, and dropped frames by the boat load. With the new CoreAVC (and new nvidia drivers...

There are several makers out there. I have used these http://www.acoustiproducts.com/en/fan_gaskets.asp, and also the arrowhead type mounts without being able to discern any great difference between the two. Either is better than screwing fans directly to cases.

Noctua do have a new model of the NH-C12P on the way (September/October?) it is the SE14 which is fitted with a 140mm PWM fan. See http://www.dvhardware.net/article36025.html.

Unless you are planning on some serious over-clocking the Noctua NH-C12P will be quite OK, see http://www.pureoverclock.com/review.php?id=765&page=4.

Try swapping the keyboard with another known good one of the same type.

The latest PWM fan that I have bought is the Akasa Apache 120mm which has a HDB bearing and a 600 to 1300 rpm range. I don't particularly care for the name or cosmetics but it is a very quiet fan. The Akasa product page is here http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&no=181...

Asus P6T is a fine board and will do everything you want. If you can afford it the Asus P6T Deluxe V2 is even better, with somewhat improved cooling and 16+2 phase power rather than the 8+2 of the vanilla P6T.

I have direct experience of these; but that goes back over four years ago to a Pentium 4 socket 478 system that I had. And that's the point - the Arctic super silent 4 ultra TC S478 - as its name suggests is not suitable for a socket 775 motherboard/CPU combination. The modern day equivalent, I gues...

I suspect that your motherboard will treat your CPU as a vanilla Q9550, not the Q9550S until you update the BIOS. So any problems in booting and running your new system are unlikely. And as you have one of the modern Gigabyte motherboards updating the BIOS is easy. The latest BIOS can be downloaded ...

The advantage of using a graphics card from the nVidia range is that they have a technology called CUDA which uses the power of the graphics chip to process video including blu-ray for either editing or playback purposes. It is supported on all post-7xxx nVidia chipsets and the 200 series, so this w...

Well the SG in ISCG stands for Silent Gaming, and it's fitted with an 800-1300 PWM fan with a Hydro Dynamic Bearing. As you would expect from that, it is aimed at gamers who just want to replace their stock cooler with something quieter. And for a Thermaltake it does seem to be rather good. Having s...

Any of the cards you mention would be an improvement over on-board sound. I have only ever fitted Creative Soundblasters, and even the budget models have sounded fine. I have had both PCI and PCI-Express sound cards, and I don't think it makes any difference what fitting they come in. If you pay mor...

As far as I can see, Intel having established Core i7 as a premium, enthusiasts CPU brand don't want it restricted to socket 1366 X58. So P55/socket LGA1156 will feature high-end CPUs branded as Core i7s, mid-range CPUs branded as Core i5s and lower-performance models branded as Core i3. In addition...

The major issues you will have to deal with in an overclocked i7 system would seem to be the power consumption, and the heat it produces. Based on the reports on the web, it would be by no means unusual to find a OC i7 system power consumption in the 350w to 400w range under load. Loads somewhat ove...
