The PC Build Thread

All else being the same what differentiates a fan like yours at around R500 to the Noctura ones that go for around R1500?

Noctua has a reputation for being very quiet, and as such provides better cooling at the same noise level than most others.
It's relatively easy to provide great cooling, the trick comes in when you want to do it without a lot of noise.

Edit: it is of course also about name, and as always the law of diminishing returns. 3 x higher price almost never equals even double the performance.

Seems that way, like this dual RGB fan Hyper 212 is only R629:

That looks like a good option for me, max fan speed is only 1600rpm so should be pretty quiet but I can't find the TDP spec anywhere even on the Coolmaster website. Without that how do you workout if a cooler will be sufficient, is there other metrics for working that out, like the CFM?

Oooh nice, if I'd seen that
But here is a snippet of testing my CPU to 100%, the fan curve is set that at 50 degrees it ramps to 69% and from there slowly up to 100% at 65 degrees, but it stopped at 56 degrees and fan speed was at 80ish%



I remember reading for the hyper 212 it was also roughly 150w tdp. Though also be wary I know Takealot is advertising the "ARGB" Hyper 212 but it's not actually ARGB, also I do prefer the clips for the fans on the Coolermaster, the others are primitive and mine has already shifted slightly off.

Now at idle

[PIF] - Repif : Hyper 212 no backplate | Pay It Forward

Re: PIF - https://carbonite.co.za/index.php?threads/steelseries-siberia-v2.398925/#post-2625039 Item: Coolermaster Hyper 212 Age: Not sure Packaging: Original Condition: Good, missing a backplate though Location: Cape Town Shipping: Sure Collection: Yes

carbonite.co.za

When I get home later I'll check what's all in the box and get back to you. Perhaps you could use that and I'll post a different PIF on carb if you are interested.

That might work but how would I install it without a backplate or does it have the AM4 backplate?

I torture tested the 3950x just now and it will hold all 16 cores at 4.2mhz under 100% Cpu load for 15mins before temps start getting a little toasty and it gets throttled to 3500mhz. The liquid cooler keeps it at around 50 degrees for 10mins before it starts to climb to 80 and then down to 60 once its throttled and then the cpu mhz climb again, it seems to go in a loop like that.

I was hoping getting the coolant nice and hot may help with the noise which is apparently an air bubble stuck somewhere but it doesn't appear to have done anything thus far.

 

[airborne]

I just worked out why my liquid cooler may be inherently noisy, the pump is in the radiator not the CPU block like most are, so that's why most of the noise is coming from the radiator which had me stumped. If only I had know that when I was tearing my hair out trying to fix it thinking the pump was in the CPU block like all the troubleshooting videos mention. Fk it!

What make and model liquid cooler is that?

Maybe this will help:

I watched that, its an Antec Neptune 240, the pump is definitely in the radiator, all those video's carry on as if liquid coolers only have the pump on the cpu block and hence go on and on about the cpu block needing to be below the highest point of the radiator.

Fortunately I found an Amazon review that mentioned it was in the radiator and lo and behold the power cable on mine goes into the radiator, finally that explains why the radiator is so noisy and the cpu block near dead quiet.

That is unusual, Googled it:

NEPTUNE 240 - Antec

www.antec.com

it does state (and show) the pump attached to the radiator (some blurb about reducing vibration on the CPU block).

Really pathetic, I would return it and ask for my money back

Apparently the 5900X, I think it is, can boost all cores to 4.5ghz but I think overall the 3950x just beats it.

If I recall correctly the 3950x is the 49th most powerful production cpu ever made, that's including server chips, the 64 core brutes.

The 5900X or 3950X can be bought 2hnd for R8k, is it normal to be able to get high end server grade cpus that cheap?

That's a made-up reason for it...what they've done is a way to get around Asetek's patent on having the pump+heatsink assembly directly on the cpu.

How did you execute and measure this?

Could do the same to my 5900x with 240mm fractal design AIO, in the name of science

Yes please give it a spin, I used Prime95 run on all cores and selected "Use hyperthreading", you can get it here:

GIMPS - Free Prime95 software downloads - PrimeNet

GIMPS has free software available for Windows, Linux, FreeBSD, Mac OSX. Contribute to the effort by using your computer's spare processing power.

www.mersenne.org

Did you run an aircooler before you went water cooled?
How noisy is your AIO?

I checked now, the 5900X is exactly one position behind the 3950X in multicore, in single core it smashes it:

Processor Benchmarks - Geekbench

browser.geekbench.com

Now that I think about it the 5900X is better due to the higher clock speeds that will help with everyday computing, the extra 4 cores of the 3950X won't come into play too often for the majority of people. But that being said the difference between a 5900X vs 3950X even in day to day stuff will probably be marginal, import 100 RAW files, save 5sec.. Boosted 4.2 vs 4.5 all cores and 4.7 vs 4.8 single core

Let me give it a bash. What did you use for temp monitoring/history, or is this part of prime95?

As far as before, no I bought a new system and specced it with the AIO from the start. It’s very quite though. I would say the “loudest” part of the system, during my normal day is the PSU - Super Flower 750W gold.

You can download hwinfo to monitor temps.

I used the msi mbb's temp monitoring app.

You can download hwinfo to monitor temps.

That would probably be a better idea.

What thermal paste is recommended?
Is the fancy stuff worth the premium or is the R50 Coolmaster stuff sufficient?

I guess it depends, I got the R50 coolermaster stuff. Not sure if paying more would've made a difference.

 

[Gtx Gaming]

These work for me, and it's decent amount of paste for R65

Read the thermal paste specifications, you want something with high thermal conductivity like around 8w/mk or more. Paste vs liquid metal vs thermal pad is up to personal preference.
