Given how poorly the Rev 2 Ninja performs vs the original version used by SPCR (even with the bolt through kit), the recommended list of CPU coolers need to be revised as the Ninja rating is now highly misleading. :shock: Was there an obvious fault with the Rev 2 Ninja, like a highly convex base? :?

Agreed - those temps seem in line with my old E4300

For that sort of money/machine, I'd get the Antec Earthwatts 380W

What if you leave the PSU so that it heats up a bit and the fan voltage is ramped up? Does the Scythe fan then start and keep running, even when the PSU has cooled enough to lower the voltage to its lowest point? Otherwise, you could just try one of the faster 80mm Scythe Kama fans (hard to tell wit...

Covering them with glue would only muffle the sound and violate the warranty I believe. Buying a new PSU would not be too Actually, the PSU noise in these cases is usually from coil whine which is caused by the coil windings vibrating. Why the vibrations are worse with low load is a bit of a myster...

I'd rather get a better aftermarket one so maybe I could push it to 3.2ghz. A decent HSF should easily let you reach that speed Artic Freezer Pro 7 - push pin The older non-Pro version has a backplate but this cooler is unlikely to cool much better than the stock HSF from the SPCR testing. http://w...

It hasn't arrived down here yet and I'm wondering whether just to get the Alpine 7 since I can get that for A$15 (~US$13). The easier fitting of the Pro would be nice, though.

More thermal mass will slow down the heat up but will not decrease the stable temp unless it also increases the surface area exposed to the airflow.

Would you notice the PSU noise during gaming ? (ie do you run your speakers at low or high volume when gaming?)

If you block the side of the Ninja closest to the PSU and run a VERY slow fan in pull through mode to the rear of the case (use the fan for case extracting and duct to the Ninja - still with the PSU side blocked), then you should achieve your aim. This assumes that the PSU fan can run more slowly th...

For a Core2 CPU, TAT is the ultimate thermal test.

Using the same motherboard (Gigabyte P965-DS3), I have not been able to undervolt my E6700 anywhere near my E4300 with the E4300 being fully stable at stock clocking (1.8GHz) with 0.99375V (bios setting) while my E6700 can only get down to 1.075V with its multiplier locked down to 6 (1.6 GHz) :cry:...

Well I'm VERY disappointed with my E6700 compared to my E4300. :oops: Using the same motherboard (Gigabyte P965-DS3), I have not been able to undervolt my E6700 anywhere near my E4300 with the E4300 being fully stable at stock clocking (1.8GHz) with 0.99375V (bios setting) while my E6700 can only ge...

The HR05+ actually comes with fan clips for higher thermal output CPUs (unlike the original version which had a duct instead).

Could you retest with a midrange Core2Duo CPU like the E6550, just to give perspective on how this cooler copes with it's intended market, rather than with a high thermal load? It would be interesting to know if the Alpine 7 Pro can cool adequately at 5 and 7 volts for one of these loaded 100% by TAT.

Yes, I agree. And if you could report back on the noise difference, that would be very useful.

I take the point that Orthos would not use all the CPU components that NeroVision would use. I did a further test with TMPGEnc in my originally undervolted config to clip the edges from some video files and that worked just fine - I would have expect TMPGEnc and NeroVision to use the system similarl...

When I set up my system, I used Orthos to test stability with different vCores until I found what I thought was the lowest stable vCore with standard clocking for my system. I tested this with 16 hours of continuous Orthos small FFT tests to satisfy myself that the system was fully stable. I also we...

I'm just a bit worried that the heatsinks in the EarthWatts PSUs are fairly small so they may need a bit more airflow when the system is loaded. That said, you're right - your system shouldn't draw much so the PSU heat shouldn't be high. I'd still prefer a temp dependant variable speed fan as it cou...

Silverstone ST50EF+ - no pins (wires directly soldered to PCB)

Why don't you run the Noctua off the PSU fan lead? Then it would ramp up and down according to the heat in the PSU.

And are you sure that the Noctua moves enough air at 800rpm if your system is heavily loaded?

My system spec is as per my signature

If your CPU is a E6300 running at 2.1GHz, isn't already overclocked? Standard for that CPU is 1.86 GHz.

I think the issue that bobkoure is referring to is that the CPU must detect that it is being loaded and then switch voltage and multiplier and this has a time lag before the CPU reaches full speed. For applications that constantly load the CPU, the speed won't be affacted but ones that load the CPU ...

Can you please state what you old system was since you have updated your sig to the new system?

I think the SLK-3800 is the same as the SLK-3000 except that the SLK-3800 comes with a PSU, so it should work. With the SLK-3000, the case is a bit wider than the height of the cage.

The Samsung HDDs are well known for having very quiet seeks but quite a lot of vibration. Even a single one can cause a case to vibrate/hum noticably. Felger is spot on about suspension being the most common way to deal with this because it is cheap and effective. Gromments are usually too thin or h...

What I'm trying to achieve with the sheets of aluminum and the styrofoam at the ends, is like what Bluefront shows in his link, but a little different. I also have an SLK-3800 case and I'd like to kick out the bottom hard drive cage. How about this? 1. load up the cage with your drives 2. place thi...

Or you just have a greater variation in requirement

2000RPM is getting up into the industrial zone, competing with Rexus or Rexon or whatever that brand is. But the minimum is 500rpm so the fan has a great range and with a good temperature based control, it can potentially give very quiet cooling at low load/temps and yet provide a lot of cooling fo...

I'd try a 120mm PWM fan like the Artic Cooling as they can be set to run very slowly at low loads and yet ramp up if the CPU is heavily loaded. This gives you both quietness and flexibility. I use one of these fans with my SI-128/E4300 and when undervolted @ stock speed, the fan always runs at ~400r...
