The Phenom II X2 550BE has been reviewed by SPCR, see http://www.silentpcreview.com/amd-june2009 The CPU cooler used for the review was the Zerotherm Zen FZ120. This has been reviewed separately by SPCR and as this page shows http://www.silentpcreview.com/article849-page2.html the Zerotherm is somew...

As an alternative to the cardboard and tape there is an official Thermalright cooler to exhaust fan duct, see for example

His temps under load were 45C over ambient... But he doesn't have a fan on the HR-01! And the system is stable. The plot thickens! 8) Unlike the OP in this thread, he has a top mounted PSU, which actually suits a hot Core i7 because it will speed up with temperature, and act (as was originally inte...

In tother words in the 40-50 range of temps. Yes, if your calculation is correct, then at 12V the same fan should be 40C over ambient, so 40C+26C=66C when it fact it is 76C. Now it was originally at 7V, and with 24C ambient it should have been 43C+24C=67C, but in fact it was 80C. So 10C hotter than...

Do you mean that the OPs cooling system is under-performing compared to what is expected? Well the OP did mention an ambient temperature of 24. It was not said what the ambient temperature was when 76C was recorded. If we assume that it was 26C, then 76C-26C=50C over ambient. Look up the SPCR revie...

Yeah, but all i7s are rated at a TDP of 130 Watts, and its unlikely that the 920 uses as much power as the 950. Wich leads me to belive that the 920 uses less than 130 Watt. ...i would guess idle usage is 10-20 Watts? So maybe around 100 Watts at load? Intel don't say all i7s are rated at 130watt T...

The behaviour you're observing is entirely normal. As you say until Windows kicks in the BIOS on the graphics card is in control, and it is set to run the fan at at a high level, sometimes 100%. I guess the manufacturers adopt this approach because it guarantees that the fan starts, whereas at 40% o...

I think you need to go for a passive PSU this time, it will solve all the noise problems.

Part of the issue here is that with a very good CPU cooler, the Thermalright HR-01 Plus and with a 920 at stock clocks, even allowing for ambient temperatures, you should not be seeing anything like 76C. I am aware that people who overclock Core i7s accept temperatures in the 75C-80C range as a matt...

Thanks for the excellent review, and I think that the CNPS10X Extreme is an impressive piece of kit. And here in the UK the cheapest price I can find is about the same as the Noctua NH-C12P so for what it is it is reasonably priced. There is a comment earlier in the thread about the CNPS10X fan cont...

I think you missed this bit from the review

"...PWM Mate can be installed on the case’s exterior by connecting with the included Extension Cable..."

You just slide the controller out of the cooler and mount it on the case using the double sided sticky pad provided.

If you like the high airflow options of the HAF 932, I would check out its recently released little cousin, the HAF 922 . It comes with slightly smaller 200mm fans but has mounting options to replace these fans with multiple 120mm or 140mm fans instead. This would give you some options if the inclu...

The key factor here as you have already identified is that you are going to be gaming at 1920 x 1080 (or maybe 1920 x 1200), and having built a system to game at this res I think it is quite a tough call. First of all the benefits of overclocking diminish as the res increases, and at that setting co...

There's quite a good (UK) review on the CX400 here
http://www.bit-tech.net/hardware/psus/2 ... u-review/1

You will need to resort to one of the nVidia BIOS editors such as NiBiTor
http://www.mvktech.net/content/view/2069/37/

It's not just about wattage calculations. I wouldn't put a CX 400 into a gaming system and to me its only virtue is that it is the cheapest Corsair CPU. It would make a good buy for people with non-gaming systems to replace 'no-name' 350-400w PSUs. For gaming a PSU with the build quality to survive ...

The system proposed should be quite a nice budget gaming system, with all the components well-matched against each other. It has to be said though that ATI recommend a minimum of a 450w PSU for the 4770. I am sure a 400w from a brand name like Corsair would be fine, but it might be worth looking at ...

Yes, the point being that if an 1100 rpm fan is not good enough, then going to 1200 rpm is probably too small an increase to make a difference. And while the increase in noise level with the 1600 is obvious so is the increased air flow. If the 1600 works in terms of air flow at least you have the op...

I think 72C is too much for a stock 920; something in the 60s would be better. There is clearly nothing wrong as far as I can see with the CPU cooler, but it still seems to me that it is simply not getting enough airflow. If you look at the Xigmatek coolers some of these use a PWM fan that idles at ...

The Xigmatek HDT-S1283 has a PWM fan as standard, so it should run at minimum rpm at idle and only reach maximum speed under load. Like most modern motherboards your particular board is designed with a PWM fan socket as standard for the CPU fan. In addition it also has a BIOS PWM fan control functio...

I also thought to purchase a noctua nf-p12 fan Noctua have an i7 cooler - the NH-U12P SE1366 - which uses 2 NF-P12s in a push-pull combination each side of the heatsink. Reviews on the web say it is a very efficient combination, coping even with overclocked i7s. But it might still be worth trying j...

If you want a completely silent keyboard you would have to go for one of the touch models, such as http://www.rsi-shop.co.uk/products/moskey-touch-keyboard-and-mouse-usb.asp Incidentally as standard this does emit a 'click' sound when keys are touched, but you can turn the sound off. With sound off ...

Core i7s run hot. Given an ambient of 24C I think your idle temps look OK. You obviously have a problem controlling load temperatures. From what is being said on the web the 920s either blue-screen or reboot at around 90C. To keep the existing cooler you could run the existing fan at full speed, and...

Arctic Cooling have the Accelero Xtreme 9800 which should fit your card, but you will need to check their web site to verify clearances. Alternatively you could control your fan manually which might enable you to trade higher GPU temperatures against less noise. The GTS 250 is relatively cool runnin...

The chances of anyone knowing about the K10 will have been severely affected by Lian Li's decision to discontinue it. So it will become increasingly hard to find. But on the face of it the combination of thin aluminum panels plus a steel chassis doesn't look particularly promising in terms of silenc...

I would recommend a PWM fan, because if you going to be gaming then you can't assume that 1000 rpm will be enough for a stressed i7 920. These CPUs as you've already discovered absorb a lot of power, and produce a lot of heat. That's why you're getting the reving and noise from the Zalman. So for my...

ooh, I thought the only people buying i7 chips were "gamers with too much money"?!?!? LOL Since 920 prices continue to drop, along with motherboard and memory prices, a Core i7 920 system or upgrade is now quite reasonably priced. And one of the main points of a Core i7 920 is how easy it is to ove...

The ability to use 2 x 4 pin plugs or 1 x 8 pin plug is there to cater for the increased power draw of higher end CPUs. On a Core i7 motherboard for example it is normally recommended if one of the Intel Extreme Edition CPUs is being used, or when overlocking.

What bothered my during the build was the Earthwatts PSU providing only a 2-pin CPU power connecter, whereas the Gigabyte motherboard manual recommended using a 4-pin. The extra 2 pins only appeared to be duplicates of PWR and GND. Perhaps this is where I went wrong?.. Are you talking about the CPU...
