I have 2 of those and they work pretty well. I do not have the VF fans so I can't compare them. The noise level is better then I expected (which I found on Optimum tech's video)After spending a bit of time with it, finding the VF-8010-PWM fan noise to be kind of like a whiny flutter at anything above 30%. Have set a pretty aggressive fan curve to avoid it and it's now virtually silent. Awaiting my chassis fan header splitter to install the 2nd.
Went ahead and ordered 2 of the Scythe Kaze Hachi. Does anyone have any experience with these?
"Duty Cycle" is terminology related to PWM operation. If you are not using these fans with a PWM header (i.e. plugging into a 3-pin fan header) then there is no such thing as '20% duty cycle'. I am guessing you're just controlling the header via voltage manipulation (as the usual with 3-pin fan headers).My VF-8010-PWM are connected to non pwm headers...they make a buzzing noise at all duty cycle levels.below 20% they stop, above 21% it goes from 1300 rpm to 3800 rpm.
Is the buzzing and rpms different when connected to pwm header?
What's the total height of this config 53-25(stock fan) = 28cm? Then add a9-14 to get to a total of 42mm? I am wondering if it will fit vk3?So...
I managed to get a 9900K running decently with a LP53 + Noctua fan combo in this case. Kind of speaks to how impressive the cooler is. Here's how it went;
I switched to this case from a Silverstone ML08 a few weeks ago and was running the below system;
8700K stock (undervolted -120mv) with a Cooltek LP53
Asrock Fatal1ty Z370 Gaming-ITX/ac
16gb DDR4 3000MHz
eVGA RTX 2080 Black (undervolted with a slight OC)
Ran relatively cool and quiet. In games, the CPU didn't exceed 80C- usually floated round 70-75C.
Then I decided to try a 9900K...
And it would throttle immediately under prime95 @ stock voltages with MCE on. I then did the following;
-Turned off MCE
-Undervolted by -100mV @ LLC 5 (the load line cal that provides least voltage)
-Set all core to 4.4Ghz
My prime95 results were: TDP was 100-110W in hardware monitor, voltage was under 1.14V and most cores didn't exceed 80C after 10 minutes
This was with a conservative fan curve. If I removed the undervolt and increased the fan speed, I could do 4.7Ghz all core without throttling.
It's not 5Ghz all core but I think this is a great compromise. Reducing the TDP by ~40% for not that large of a step down vs. stock.
Velka 7 should be released this May, although it has been designed for smaller hardware than you expect (you can disregard all of my previous design ideas mentioned in this thread).Hey guys,
Have we heard any updates about the Velka 7? I've been wondering about it for a while.
Sweet! Can we expect a teaser before the release? Gotta figure out if I buy this or the 5, which has been my plan so far.Velka 7 should be released this May, although it has been designed for smaller hardware than you expect (you can disregard all of my previous design ideas mentioned in this thread).
Big upvote on this. All I'm really hoping for with the 7 is some watercooling support. I really liked your previous idea of what was essentially a smaller Ghost + L tophat, but I'm excited to see what you've changed!Sweet! Can we expect a teaser before the release?
