Nepton 280L - Temperatures too high?

Recommended Posts

Lee T    0

Greetings all.

 

I've been lurking these forums for the last few weeks, i managed to get a Nepton 280L for under £50 the other week and it wouldn't fit into my case, so I ended up building a whole new PC (I was in need of a bit of an upgrade anyways.

The first one I had to send back as pieces was missing from the box (amazon) and the screws wouldn't fit into the radiator (wasn't anything for them to "bite" on.

 

Anyways I have:

  • CPU: I7 4790k
  • Mobo: z97x Force Soc
  • Case: Source 530 - NZXT
  • PSU: Asaka Venom 750w
  • Fan Controller: Bit fenix Recon.
  • Ram: Corsair Vengeance 1600 8gb
  • Fans:  NZXT FZ200MM fan in the front
  • GPU: 660 GTX SLI

2 fans at the bottom and 1 fan on the back of the case. All pulling from bottom to top.

 

I have the 2 dual fans in the splitter plugged into my CPU_FAN, and my CPU coole rinto CPU_OPT the other way around and the fans wouldn't work they would spin very slow or not at all.

The rest of my fans are controlled by my Recon and have a case temp of about 28c over all 5 sensors, placed around my case..

I have installed the Nepton 280L at the top of my case, with the fans pushing air through the radiator and out the PC.

The airflow coming from the Radiator doesn't seem that hot coming out, its about 22c in my room, my idle is about 40c+ when i start typing (writing this message i'm getting 50c+.

 

Speedfan, won't even detect the fans to control them, yet my eztune (gigabyte) will detect it and controls and says its working around 5000RPM just typing this and 1100 on the fans.

I've reseated my cooler 2x already over the last week and still getting temperatures that are a little higher than I expected from the reviews I have seen and my old build which had a Cooler Master Hyper 212 EVO in it.

And have applied and cleaned new thermal paste each time.

 

If i run prime95 on blend test I get temps of around 75c If i run, Small FFTs it reached over 100c so i hit stop straight away.

I've built a number of pc's in the past.

 

I've not overclocked my system and am randomly getting a freeze, which lasts about 10 seconds where all apps stop responding and then clear up again when my CTRL + ALT + DEL screen comes up.

 

I'm trying to rule out what it might be, I tried to test my ram but had it lock up on me before it could complete.

I will be ordering 16gb next week if I can't resolve the temp issues if they are normal for this cooler (websites seem to state different).

 

Any advice on why its running so hot, what I need to change etc would be greatly appreciated before I start looking at RAM etc.

My HDD, SSD, Ram and GPU are all from the old PC and was all wiped before I put into new PC.

I'm unsure if I maybe have missed a setting in my BIOS or something which effects it.

 

Thanks.

Lee

Hello Lee T,

 

The CPU Fan 1 and CPU OPT headers are linked together so it is not recommended to have your pump connected to either of these headers. I would suggest connecting the fans to CPU Fan 1 and CPU Fan OPT. Then connect the pump to a different header on the motherboard such as System fan or Chassis fan.

 

I would also suggest reinstalling the pump since you are receiving such high temperatures. It's possible that its it is not making good contact with the CPU.

Respectfully,
Patrick

Greetings CM Patrick, Thanks for your reply.

I have reset my CPU and cooler again and changed the location of the fans, but I did notice in my BIOS that my CPU Fan and CPU Opt can be controlled separately in the options which is why i had it setup like i did.

 

I have changed the thermal paste from the one that came with the Nepton to an Arctic 5 and as I'm typing this the cores are fluctuating from 32-40's. Room temp is 21c.

I just ran a 5 minute prime Blend test and got temperatures of around 60-70 over all cores.

Which does seem a bit better than what it was.

 

There doesn't seem to be hardly any heat coming out of my pc, and my Fan controller says the case temp is around 25-28 over 5 sensors.

What sort of temps should I be expecting as in the summer my room gets alot hotter (I live in UK so wont be massively high, but still can reach double of what it is now.

 

Thanks.

Lee.

 

@edit.

Well, I just walked away from my PC for a minute it was idling and I heard a beep from my fan controller (the Nepton isn't plugged into it). My temps just reached over 100c not doing anything. It appears the radiator "stopped" working for no reason and the fans went into full force trying to cool the CPU down..

 

I'm about to send this back, first was faulty and now this one is doing this, please provide advice.

Hello Lee,

 

Ok I apologize usually the CPU Fan 1 and CPU Fan OPT are linked so you can adjust the RPM for push/pull fans together without using a Y splitter.

 

From the information you provided, it appears that the pump may be defective. I would keep an eye on the pump RPM. If it is displaying a 0 or N/A then it is not working properly.

 

May I ask where you are located?

No need to apologize for the CPU Fan 1 and OPT suggestion, so many motherboards out there, I doubt you know every single BIOS setting :)

The pumps been working fine for the last 5 hours that my pc has been on. It was runnning at 0 RPM when i logged into my bio settings, yet now its running up to normal speeds.

 

I am unable to give live feeds of the 2 fans and the radiator without going into the BIOS, I could install Gigabytes software to look at it but I heard of problems with the in windows settings messing up the BIOS settings and them to freak out (maybe my problem? but without the software installed?)

 

Speedfan, HW monitor, and a few other tools i've look at are register 0 RPM on fans 1-5 but register my core temps are 28-40 while typing this.

It seems to be running a cooler now i've switched over the CPU Fan 1 and OPT to the fans and then the pump to sys fan 1.  (which is strange why it won't detect it) and also changed the thermal paste to the Arctic 5.

 

Would you happen to know the rough temperatures that it should "idle" at and just normal use like word processing etc?

 

I'm located in UK.

Thanks for your fast replies.

Hello Lee T,

 

Most Intel CPU's idle between 30-35c and you will probably see around 60-65c during gaming.

 

Please let me know if you have any more questions.

It seems problems were short lived.

When I go AFK from my PC it appears my radiator shuts down or partially shuts down, I came back to my PC beeping at me for temps above 70c.

I was sat in bed watching my NowTV box, when I noticed my fans starting taking off (full speed), as soon as my pc turned off the monitor etc like it does when its been idle for so long.

 

Whats the crack? this is the most annoying water cooler I've ever had my hands on. I'm not willing to risk a brand new CPU, mobo etc for the sake of a VERY VERY VERY loud (plane taking off the runway) and very "works when it wants to cooler".

Just a quick FYI, the radiator can't shut down as there isn't anything that moves in the radiator--what you're referring to is probably the pump. That said, can you have the pump directly connected to the power supply instead of the motherboard?

 

Your situation is definitely out of the ordinary, so I want to see if taking the motherboard out of the equation will yield any positive results. 

 

When the temperature gets that high while idling, is the pump off?

Sorry cool beans, I meant the pump i consider the unit "whole". My apologies on that one.

I've put CPU Fan for the pump, CPU_OPT for 1 of the fans and sys_fan2 (cable won't reach fan1)).

It seems the pump is always running now on CPU_Fan as before the radiator was "disabled" randomly and temperatures skyrocketed.

I've re installed gigabyte System Information Viewer, and can see the fans running full speed.

CPU_OPT speed scales as does sysfan_2.

 

I'm sat looking at temps of around 22-27 while typing this message, where as before it was alot higher.

I'm thinking there are compatibility issues with z97x Soc Force bios/gigabyte fan controller and this cooler (or maybe coolers in general, I've still got my old CM Evo if worst comes to it, I will switch back to that.

 

I'm going to mess with the workload% and fan speed settings to see if i can get the fans to work a bit better and more constant speeds as when they are full speed its way too loud for my bedroom and my front fan controller only detects the heat inside the case rather than the CPU so i can't see temps while i'm  not looking at speedfan or SIV.

That's better. I also have the Z97X SOC Force, I had no problems at all (for so far).

 

Cheers, Pim
