Hello there.

I've put this on reddit but I think nobody even read it. I have no idea where else to post this, so here I go.

Today I have changed some case fans and thermal paste but I'm not noticing any improvement, in fact, it seems that the CPU temperature is slighty higher. I don't know if this is normal or if I've done anyhing wrong. The number of fans is lower now, but I don't know if that's really important for the numbers.

Let me explain to give some insight, because I'm quite lost and I don't know who to talk with about this... Since I've seeing this kind of threads before...

Where I came from:

  1. ​3 Intake fans, 1 phanteks, 2 bad cheap fans.
  2. 2 exhaust fans, 1 phanteks, 1 bad cheap fan.
  3. Typical Cooler Master evo212 as CPU cooler, one fan (the one from the cooler)

What I've put today:

  1. 1 intake fan, phanteks
  2. 2 exhaust fans, 1 phanteks, 1 arctic
  3. Another fan to the Evo 212. One intake, one exhaust. The exhaust one is the one at the back of the case. Brand is arctic..

Silly draw of how it's now:

ART

Currently there are 3 fans that can't work because I'm waiting for some splitters. Original plan was to have 3 intakes at the front... and 2 exhaust at the top of the case.


What is going on:

​CPU temperatures are up. About 45ºC on idle and 67ºC tops while playing... Last time I've checked was 58ºC while playing... So it's 9ºC difference... :( However, although the number of intake fans has decreased, I doubt it makes a huge difference... also those fans were very bad quality. I've also put the case on the floor.

​At this point in quite frustrated because I have no idea why is this happening. ​Maybe I wrongly check the temperatures before the fan change, but I've checked more than once (never saced a screenshot) and always was okay, nothing worrying.

I think i've put not enough thermal paste or maybe 2 fans on the CPU cooler (intake and exhaust) is a silly idea... I can't afford a D15 but there are 212 models with 2 fans. Another thing that could happen is that the cooler is not correctly placed, but was firmly and nothing felt loose...

Extra information:

​1. All of the fans are connected to the motherboard, which is a z170 Gygabyte gaming 5

  1. CPU is an i5 6600k with a very very light OC (Currently at 4.0, was a 4.2)
  2. Had no issues with temperature before... However I think they were always a little bit high because of the summer, is very hot and humid. Got worried recently because of hot waves and rising numbers.
  3. Used HWMonitor to check temperatures.
  4. Changed Fan Curves on the bios, howver I think the Arctics are not PWM.

Any ideas? what can I do to fix this? Any tips?

Thanks bunches

I'd blame changing the CPU fan, and maybe the thermal paste you used wasn't very good?
The lack of intake fans MAY make a bit of a difference, but probably not that much, it's always good to have good flow.

I used the cooler master paste, which I know it's not the best but neither the worst.

I've checked temperatres with other games are higher was 58ºC. Seems that only one game is the one with the spikes.

I could get some better paste and change it in the future or purchase it with the splitters so I can improve the intake flow and the paste at the same time.

The temp depends on the game and how it uses CPU.

So one game can give you 50C while other will give 70C.

Isnt TjMAX 105C so why does 67C at high load matter?

Intuitively, there is a possibility that CPU grease did not go well.
(Air entered, cleaning was not enough, etc.)
However, is there a possibility that the motherboard side is automatically overclocked as a desire?
(Easy Tune *App)
i5 6600 k ...? idol 39℃ benchmark/game average 78℃
Do not worry.

because one intake and two exhaust.
turn the top exhaust into another front intake.
and even a bad fan moves more air than no fan. so why not keep the old setup?

why do you need the splitters? don't you have enough fan headers on the mainboard?

you could take off the cooler again and check the spread of the thermal paste just to be sure.

I need the splitters because I'm stupid and didn't plan as I should.

So the cheapest fans that I had had 3 pin and molex but the arctic have only 4 pin. Motherboard has 3 sys fans slots so I need some splitters to use the fans.

Cheapest fans had only 1ºC of difference between 1 intake and 1 exhaust (phanteks originals that came with the case)... Changing those was a very old plan that I have. Having them were almost no difference :/

what case are you using then? the modern ones love their closed off fronts.
looks nice but cools like shit and you will need more and / or stronger fans in the front to overcome the resistance.

P400.

While I recommend it and I think it's a good case, I won't purchase it again.

DH15 doesn't fit by 1 cm, the front filters are tiny and modern cases have better space mangement overall.

looking at some older reviews the P400 is a hot box with pretty poor cooling performance.
not much you can do about that except tossing it in the trash.

with a closed off front like that you'll want more than one front intake and you might even need to give the front ones some more rpm to fight the obstruction.

What others metioned 60-67 is just nothing to be worried about, i ran 80 on my old pc, especially if you live like where it's always 30+ it just happens, or remove that small overclock.

If I'm not mistaken, actual performance was quite similar until eight generation, so... we need an upgrade :P
