*temps were recorded on an overclocked 4.3Ghz 1100t at 100% load. These are "Core" temps, not socket temps.

50C - AP15
48C - Stock 920 fans
44C - AP31

What was the duration of those tests?

Seems like the AP-31s would be the better option if they were quieter than the stock fans and you can utilize the ChillControl software. Just curious but what's the noise difference like between the AP-15 and AP-31 fans? Any videos?

4C difference is a decent difference considering this is only a fan replacement.

I don't have any videos, but the noise difference between between the AP15s and AP-31s at max speed was at least twice as loud.

It's a considerable drop for just fan replacements, but that is at max speed, which is again, screaming loud. at similar RPMs to the stock fans, they were a bit quieter, but the same performance, the AP-15s are much quieter, for a little less performance.

If my ambient temps were higher, or I was getting close to overheating a proc, I would definitely use the AP-31s, but since I'm not, and since the wife gets a vote, I'm using the AP-15s.

Only 2C difference going to ap15's; adding a shroud should compensate for that.
Now i just need a confirmation that they run @ full speed conected to the 920.

I just installed my Kuhler 620. I have used many, many heatsinks and closed loop water systems in the past, and I can say that I am happy with the build quality on this unit smile.gif

Performance is a bit weak, but I may just need to reapply the thermal paste, as I got a bit overzealous with the MX-4. Right now it is performing on par with my 212+, both units using push/pull AP-14s.

I'm hitting 63C in Prime95 @ 4.4Ghz on my i5 2500k (Before extensively tweaking voltages and such). Ambient temp is a bit warm at 26.5C These types of units are heavily dependent on ambient temps wink.gif

I will re-seat this puppy after I move, but for now it'll work just fine. I primarily picked it up to get a better view of my motherboard, to accommodate 16GB of Ripjaws-X ram, and to better facilitate GPU cooling.

Also, having installed several H50s and H70s, installation of the 620 was a breeze for me smile.gif

Here is a picture of it in action smile.gif

On the topic of AP-15s, I find them to be too loud. AP-14s are the perfect balance of performance and noise for me. I use AP-13s in my quiet and ITX builds. My GF is using a SUGO05 ITX build with a H50 and push/pull AP-13s smile.gif It's near-silent.

Well atleast I don't find AP-15's too loud tongue.gif
Yes, you CAN hear them at full speed, but I think it is mainly the air gushing through the radiator.
BUT, it is personal. Someone may even find the AP-13's too loud lolol

And I've been too thinking about putting shrouds on my radiator but haven't "had the time"
I need some zip ties and some ingenuity to mount them with the shrouds.
Since I couldn't find anywhere here locally same kind of screws the antec uses, same length or longer.
They were either too thick or too thin.
So currently I have the fans mounted to the radiator with 2 screws per fan. Works great!

But do you guys reckon there would be a noticeable difference for having a shroud for only the push fan vs having shrouds for both push and pull fans?
I've seen a test somewhere on the internet about the no-shrouds vs shrouds but I can't remember anymore WHERE I saw that. Care to help?

Also I am currently testing my 2500K with 4.8Ghz@1.368v
Temps being around 60-70-68-65 core0-1-2-3
Ambient temp is a tad lower than I usually have since it's a bit of a cold night and I've my window open with a 30cm table fan blowing cold air from outside towards the 620 rear intake of my case.

The kind of sound AP-15s produce is MUCH less offensive than typical fans. It's too loud for my taste, but it is very tolerable compared to alternatives in the same RPM range. I love GTs, they are a triumph of fangineering smile.gif Best. Bearings. Ever. smile.gif

In my opinion, Noctua P12 is more annoying than the AP-15's
Since I have the top cover off of my A05N case because of heat build up on top of the case -> I ghetto mounted 2x120mm fans on there blowing air down.
Dropped gpu temps 20*C

One of the fans is GT1450rpm and the other one is a Noctua P12.
With the P12 you get the funky blade design with uberspecialvortexnotchforubersilentoperation which make the fan whail.

When I have the GT1850's at top speed, I can CLEARLY hear the P12 when I ramp it up from 5V -> 12V
And the pricing for P12 is just plain ridiculous..

I think I'll now mount one shroud to my 620 smile.gif
But I gotta find another zip tie. I'm kinda on a short supply of them biggrin.gif
Found one. But I need at least 1 more. biggrin.gif
Time to get creative biggrin.gif

Just installed this along with new mobo and ram... one thing to say, no three things to say really quiet, also VERY capable of cooling the cpu in every mode, and in extreme mode= OMG!! ITS LOUD. like Really loud. but still worth every cent, it's like with every DB of sound you get a buttload of temp decrease.. anyway, I bought it, and I love it!
