Changed case fans, now getting higher temps

[iHomer]

So previously I had NZXT AF12 (3pin) fans installed in the case.

- 1 x rear exhaust

- 1 x top exhaust

i.e. the default case fan layout

 

Now I've got:

- 1 x rear exhaust - Noctua NF-P12 PWM 1700

- 1 x top exhaust - Noctua NF-P12 PWM 1200

- 2 x front intake - Noctua NF-P12 PWM 1700

 

Before I was getting around the high 70's in CPU temps (Cinnebench R23)

Now I'm getting 83-85c CPU temps and sounds way louder (main objective was to get PWM fans to control the noise level)

 

Any suggestions or ideas?

Should have added:

tried two fan curve configurations:

- standard

- 25% @ 50c, 50% @ 60c, 75% @ 70c, 100% @ 80c

[iHomer]

Should have also added:

- Case is the NZXT H510

Set them all to 100% and see if its still overheating. If so you may have bumped or done something to the cpu heatsink.

I should also mention,

Upon booting the fans do spin to 100% twice then calm down.

Is it anything to worry about?

What heatsink / cooler are you running?

stock cooler that came with R5 1600

I'm noticing that when the cpu temp shows 83c (HWMonitor)

the exhaust air is barely warm

[diediedie295]

Strange

 

I know that those fans are more pressure optomised than the stock ones but it shouldnt really have massive differences. 

 

With regards to the 100% at startup dont worry, mine does that also until the fan control kicks in and shuts half of them off

I just can't understand why I'm seeing such a big difference in temps

maybe instead of:

- 1 x rear exhaust - Noctua NF-P12 PWM 1700

- 1 x top exhaust - Noctua NF-P12 PWM 1200

- 2 x front intake - Noctua NF-P12 PWM 1700

 

do:

- 1 x rear exhaust - Noctua NF-P12 PWM 1700

- 1 x top exhaust - Noctua NF-P12 PWM 1700

- 1 x front exhaust - Noctua NF-P12 PWM 1200

- 1 x front intake - Noctua NF-P12 PWM 1700

 

?

If you're really concerned about noise I would invest in a better CPU cooler and anything above $25-$30 like a Hyper 212 series or equivalent will beat a stock cooler by miles. This will bring CPU temps down and therefore noise.

I'll definitely look into it - should be around £20 in the uk

just strange how temps overall have increased.

I was under the illusion that Nocuta were known for their quiet and high performance fans

[diediedie295]

I wouldnt place a intake and an exhaust at the front, theyll just end up fighting each other. Also with the H510 having a solid front panel theres a limit how much air youll get through it via the side intakes. Large amounts of tempered glass and solid panels leads to higher temps. no getting around that. 

[diediedie295]

Noctua fans are excellent, i have many myself but if you dont have the raw surface area to dissapate the heat you can have the best fans in the world and it wont make any real difference. Stock coolers are adaquate and thats it. The dont really care about noise and or temps as long as they are within limits.

Just strange, even under some regular style workloads like handbrake

temps just seem to keep climbing 

ugh

In terms of a replacement cooler, if your motherboard doesnt have great or any VRM cooling id recommend a down draft cooler to keep supplemental airflow over the board. It'll help increase the lifespan of your parts.

Not a little strange how NZXT included case fans work better than 4 nactuas?

[diediedie295]

The noctua redux P series of fans are designed for static pressure. Based upon the design of the H510 it is better suited to airflow fans as theres no restrictions insdie the case in the form of HDD cages or radiators. The stock fans are airflow optimised judging by the style of the blades and they perform better in unrestricted airflow applications.

 

I persnoally noticed a difference going to NF-F12 pressure fans in the front of my case as it has HDD cages in the front and therefore can be restrictive.

What do you think I should do?

Go back to the old config?

[diediedie295]

Personally, i'd try 2no. of the NF-P12 in the front as the static pressure my help and put the stock fans back in at the rear and top and just take a measurement and compare the results.  Also just check you CPU cooler hasnt come loose just as a precaution as mentioned above. 

 

Id deffo upgrade that cooler even if you dont plan to overclock. Running the CPU at lower temps in never a bad thing. 

 

Also try tuning you fan curves, it may take a while to get it right but dont give up. Took me ages to find the right balance for my system.

 

I doesnt make sense your gaing temps, just check the airflow channel using your hand or a scap of paper to visualise the airflow path. Also uses your GPU temps to guage performance changes

Update: after playing about with the fan curve I'm getting 81c under full synthetic load and idling at around 49c.

 

Handbrake encoding at 82c

 

Plan on using this fan curve when gaming and a silent pre-set for work etc 

 

 

[iHomer]

Might try:

- 1 x rear exhaust - Noctua NF-P12 PWM 1700

- 1 x top intake - Noctua NF-P12 PWM 1700

- 1 x front intake - Noctua NF-P12 PWM 1700

- 1 x front intake - Noctua NF-P12 PWM 1200

[iHomer]

All sorted

 

min 36

avg 45-52

max 72 (100% load after 30mins)

 

config:

- 1 x rear exhaust - Noctua NF-P12 PWM 1700

- 1 x top intake - Noctua NF-P12 PWM 1700

- 1 x front intake - Noctua NF-P12 PWM 1700

- 1 x front intake - Noctua NF-P12 PWM 1200

There is a reason why it has 2 exhaust fans only when stock. The case has very bad airflor and thus completely relies on negative pressure for cooling.

well... using a 3 in and 1 out config work better now

and much much quieter
