Airflow vs static pressure fans. Are they a scam?

[freeagent]

That's the maximum rpms of that thing and it's good enough to cool anything that you can buy.

I don't know.. looks very mid range to me. I wouldn't put it on my 5900. My 5600 maybe if I didn't have another cooler. My 3 main ones right now pretty much destroy it. Looks like it does ok with a quad core.

Mugen 5 is good, but mainstream compared to Fuma 2 which pretty mainstream too(noisewise).

Oh well... That's disappointing for sure, but from all data they seem to be good and sometimes chart topping fans. I have bought some other Arctic stuff and its quite solid, fan being out of balance seems like manufacturing defect. I hope that you can RMA them.


Out of curiosity, what can happen to bearing if it is spun too fast?

It burns up/degrades the lubricant, leading to even more friction. All bearings have races and once the lubricant is gone the race could be scored.

Thats not at all the same thing. Engines use fluid bearings, no balls in them. the valve train is what takes a shit first, and then possibly the pistions will seize as the oil gets too hot and gets burned off the cylinder walls.

Not all engines use fluid bearings for the crankshaft. Smaller 4-stroke engines still use roller bearings for the crankshafts.

Well, I have Mugen 4 PCGH. It is an excellent cooler. It does cool FX 6300 passively in not so well ventilated case. with fans it can take it to 5GHz+. It wouldn't have any problems with i9 11900K. Mugens generally aren't chart toppers, but they certainly high end performers. They certainly are chart toppers in noise benchmarks. Considering that I got mine for 55 Euros, it's certainly a good value cooler. It was literally more than thrice cheaper than NH-D15 and it was within 2% of performance difference. Not sure how much TweakTown is to be trusted, but they reviewed normal Mugen 5 and it certainly performed very well:

Scythe Mugen 5 Rev.B CPU Cooler Review

Scythe's Mugen 5 Rev.B is one of the best CPU air coolers we have reviewed in recent times. Why? Come and find out.

You are really underestimating these coolers. I'm quite surprised that TPU never reviewed any Mugen version.

Looks pretty decent. Nice to see my Le Grand Macho RT in there kickin up dust. I would still be using it, but FC140 handles my Ryzens better.

Imo Ryzen is a trainwreck in terms of heat dissipation. It's very internally bottlenecked by its layout. You know Ryzen is bad at transferring heat to cooler, when you realize that 5950X has a power consumption of Athlon 760K and yet runs a lot hotter. My old FX 6300 technically should run a lot hotter than 5950X, but oh well, it certainly doesn't.

Oh yeah I know this. While you were running FX I was giving Mother Nature the finger with my highly clocked x5690.

 

[looniam]

Could you link me an example of that?

in case you're still looking.

Thermalbench.com

cheers.

I don't think I was doing any favours for mother nature by using FX either. I once cranked it to 5.288GHz.

Dude I have iPPC 3000s on my CPU, it is far from silent unless you are completely deaf. I have my PC in the basement, if I turn my fans up all the way I can hear it upstairs on the other side of the house. Most consumer fans are weak to me lol..

Three IPC 3000 120mm and three IPC 3000 140mm Noctua fans, 3x rad and 3x case fans, all running at full 3000 RPM speed. And I love it.

I did wonder what a case full of them sounded like.. might have to take you up on that lol

Edit:

Amazon.ca is out of 140s.. I may sneak in a couple of 140 2K temporarily and I can use them on my other pc when 140 3K comes back in stock.

I can get them from the states, but they were on sale and now there is a seller on there that has them listed for double price. I could line the case in 120s.. the price of those fans has me considering a new mobo and hand mine off to the kids machine.

apples to oranges mate. the thermal sensors are not reading the same points. FX series actually idles below ambitent temps meaning its being offset for quiet fan profiles or who knows why. The TJM was what 75deg on FX? As for older CPU's most of them were reading cpu socket temps hence why the old 60deg C was considered max temps. So every cpu evermade has been a thermal trainwreck when you push them to the limits. hence why back in the day they limited clocks so much, they knew more clocks wont really net that much more performance at the cost of much higher power draw and temps leading to more warranty cpu's because people never watch cpu temps. But its a bit of a differnt world now. so many years of OCers talking about how they want clock speed actually changed the market. Reviewers are looking at game performance like never before. all this helped to change the state of current cpu's and how they are marketed. (for better or worse)

Not a bit noisy?

I only have two and they are pretty loud when they spool up. Of course you can set limits but that’s no fun..

It was 62C, later changed to 72.4C.

FX had CPU sensor, but it had temperature offset for some reason.

So every cpu evermade has been a thermal trainwreck when you push them to the limits.

No, just no.

hence why back in the day they limited clocks so much, they knew more clocks wont really net that much more performance at the cost of much higher power draw and temps leading to more warranty cpu's because people never watch cpu temps.

Duh, that's like exactly like today and nope they pushed clock speed a lot. FX 6300 Turbo was 4.1GHz. FX 6350 turbo was 4.3GHz. FX 9590 had base 4.7GHz and Turbo of 5GHz. 9370 had base of 4.4GHz and Turbo of 4.7GHz. i7 4790K had turbo of 4.4GHz. That's just a bit less than today.

But its a bit of a differnt world now. so many years of OCers talking about how they want clock speed actually changed the market.

Not really all that much.

Reviewers are looking at game performance like never before.

Just like they always did. If they didn't, we would still be fine with 3dfx VooDoos.
