What fans to buy for OC

[Indivision]

Hello,

I want to buy some new good fans for my radiator. I am currently with EK SLIM 240 ,

I replaced the EK Vardars (1850RPM) with Corsair ML120 120mm Magnetic Bearing Fan - Dual Pack (2400 RPM) but my temps are even worse....

https://www.scan.co.uk/products/120mm-corsair-ml-series-ml120-dual-pack-7-blade-premium-magnetic-levitation-fans-af-sp-combi-400-240

So I want to buy one more radiator EK 360 PE and put new nice fans but I don't know what to choose and what is the difference between them.

I am going to do 5ghz on 8700k ( Not delided) with the vardars I get 75-80 degrees for stable machine)

Currently I'm looking at

https://www.scan.co.uk/products/120mm-corsair-ml-series-ml120-pro-led-single-pack-premium-magnetic-levitation-fan-translucent-white-

But as I see there is a bit difference the RGB says Hydraulic Bearing and the LED one says Airflow/Pressure and I don't know what is the difference, also i need advice about the fan speed, for 3x fan do you think 1500 will be enough for good temps for 5ghz when i will have second radiator 240 with 2400rpm fans going to it as well..?

Please help.

Thanks!

You want fans with high static pressure for radiator fans.

If you don't mind not having LED on them, then these are pretty good: Cooler Master Silencio FP120 PWM 2400

The difference is that the LL uses a bearing and the ML uses magnetic levitation. The main difference is that at the same noise level for either of them, the ML will be spinning faster.

From looking at the EK fans it looks like they might not be controllable. Or they are only controllable to an extent.

The ML fans you bought are 100% controllable and go up to 4.0mmH20, where the EK fans appear to only go up to 2.2mmH20. That would make the ML fans vastly superior but only if they are at the loudest setting so if you did not change the speed they would be roughly 50% speed and yes worse than the EK's. The great thing about the EK fans is that they are pretty silent even when up pretty high, making them great-all around fans.

I would also look into a Corsair Hydro H115i (not the Pro).

I have that with 2 ML140 Pro's and even at 800rpm and running the pump in quiet mode I am able to keep my 8700k under 75c at stock under torture loads. The loudest setting keeps it under 65C at torture loads. Gaming temps even in quiet mode it stays under 65C and you can't even hear it. My Xbox is louder than my PC by a lot.

Run your radiator fans in pull rather than push, if possible. You'll see either same results or slightly better and will extend the lifespan of the fans (and run more quietly).

I am going to buy EK Vardar 3000 RPM 5x for both radiators, so 240 20 thick and 360 38mm thick +5x 3000 rpm should be ok for good overclocking, I will add GPU in the next months so that's why I will add the second radiator now.

What do you think?

Also I am using 750W G2 evga for i7 8700k, msi 1080ti gaming x, Asus prime-a z370, 16gb ram 3000 MHz, 5 case fans and 2 CPU fans, Corsair crystal 570x , do you think this PSU is enough for this?

Have you calculated system load? 750w should be plenty, but this is a good exercise in understanding how you determine this.

For the fans, sure. Seems fine. You could also get by with the single 360 radiator alone if you wanted.

Well, I will have 2 anyway so ... XD better used them both

No one will criticize you for over-radding a loop. Since radiators are some of the least restrictive components in a loop, it is often worthwhile to take advantage of more heat exchanger volume.

Hm ok , well thanks mate , just last questions I'm considering to buy of these fans please help me to choose one model

https://www.overclockers.co.uk/noctua-nf-f12-industrialppc-24v-3000-ip67-pwm-120mm-fg-061-nc.html
as I see 7.63 static pressure 3000 rpm and 44 db which is low for that high I think

https://www.overclockers.co.uk/ek-water-blocks-ek-vardar-evo-120er-rgb-500-2200-rpm-fan-120mm-fg-00b-ek.html
tis is 2200 rpm Vardar RGB
3.73 static pressure only but still double on what I have.

I personally like the EK Vardar fans, and as someone who uses 3000 rpm Ultra Kaze fans for my benchmark watercooling tests, 3000 rpm fans can get very loud. I've tested the Vardar fans on both the EK Predator and the EK A120 kit and they are very solid ~2k fans Of course, this is nothing against those Noctua fans...but are you also aware they are 24v?
