[SOLVED] My cpu fan speed

[lordofthenecklaces]

My cpu fan currently spins at 1770 rpm max (under load)Cpu temperature goes up to 80'C mostly around 73-76 .My question is İs my fan too slow or is there something wrong with the airflow of my case

 

[Aeacus]

Without any additional info, it could be one of several things:

• Too high OC on CPU for CPU cooler to handle
• Too small/weak CPU cooler to cool CPU, even without CPU OC
• Very poor airflow in your PC
• Dust filled heatsink/rad
• Dried out thermal paste between CPU heat spreader and CPU cooler

All those above can be fixed in one go by going with better cooling capacity CPU cooler than you currently have. Or you can attack them one by one when keeping your current CPU cooler.

CPU cooler fan RPM doesn't say us anything since there are CPU coolers out there where fan doesn't spin fast at all. E.g my Arctic Freezer I32 stock fan spins at max 1350RPM.

-I dont overclock my cpu and if there is bad airflow wouldnt my other parts heat up aswell ?

 

[Aeacus]

Other parts have different heat resistance and head dissipation than CPU. For CPU, only way to dissipate it's heat is through CPU cooler. GPU, HDDs dissipate heat through their casing and HDDs doesn't get that hot either.

Fact is, your CPU is running on the hot side. And without full sys specs, i can't tell if the CPU itself is the hot running one (e.g i7-7700K is one such CPU) or is the issue somewhere else.

My cpu is İ5 3570 paired with 1050 ti h61m ds2 for the motherboard
Cpu is about 5 years old ı think same goes for the motherboard aswell
The problem is ı dont know if its just the cpu like you said it could be the airflow aswell and ım planning on getting a new cpu atm but if the airflow is the problem then ı could just buy a new case and be done with it

 

[Aeacus]

Your i5-3570 isn't naturally hot running chip. If you'd have i5-3570K with medium- to high-level OC on it then yes, you'd be seeing such high temps out of it.

Also, your current case, with case fans and fans orientation is?

 

[lordofthenecklaces]

I dont know the model of the case but ı think theres 2 fans in it 1 on the side panel and 1 for the cpu.My cpu fan is Evercool 1156-15.And also if it means anything the my pc case is really tall ı believe they are called Tower cases

 

[Aeacus]

Is your CPU cooler looking like this? Since if it is then do note that it's fan can spin up to 2000 RPM (+/- 10%). Also that CPU cooler is one of the worst ones due to it's very small size (especially heatsink size).

As far as PC case goes, you can take a pic of it and upload to any image hosting site, afterwards, linking the image here.

But this much i can say that 1x side fan (most likely intake) isn't nowhere near enough for proper PC cooling. Bare minimum would be 2x fans: 1st one at the front as intake and 2nd one at the rear as exhaust. Since with 2x fans, you can have some kind of directional airflow inside your PC.

For example, my Skylake and Haswell builds, full specs with pics in my sig. In there, per PC, i have:
2x 140mm front intake fans
1x 120mm bottom intake fan
3x 140mm top exhaust fans
1x 140mm rear exhaust fan

Idea to get the best possible airflow with the least amount of noise is to install as many fans in your case as possible. Preferably 140mm rather than 120mm since 140mm fan moves more air and does that more quietly than it's (same spec) 120mm counterpart.
While installing 5x to 7x fans in your PC may look like that you'd get extremely loud noise out of your PC, it's actually vice-versa. The trick is that the more fans you have inside the case, the less each fan has to work to maintain the airflow and the less noise fans produce.
And that is also a main reason why i have 7x high-end case fans in my Skylake and Haswell builds. Mostly 140mm but few 120mm as well. Since i have that many case fans, i can keep all of my case fans spinning between 800 - 1100 RPM and thanks to this, my PCs are very quiet while still having proper airflow inside my full-tower ATX cases.

For you, all you may need is 1-2 additional case fans to lower your CPU temps. But without knowing which PC case you have, i can't suggest if to go with 120mm or 140mm fans and also how many you should buy.

When was the last time you pulled your PC out from where it's sitting, opening up the side panel and cleaning the insides from dust? Since where your PC currently sits, it has high chance of getting quite a bit of dust in it.
Did you know that if you elevate your PC only by 6 inches (15cm) from the floor, you can reduce the dust intake by 80%?

Though, based on that image, i can't identify your PC case. Closest i found is Sentey Stealth (specs) but that's not it. But what i do see is that you have minimum of 1x 120mm front intake fan since i can see it's blue LEDs. It's possible that you also have 1x 80/120mm rear exhaust fan as well since many such "gamer" cases usually come with 2x fans. And some can even have vents with fan mounting holes at the bottom and/or top where to install additional fans. But in order to know for sure, you need to open the side panel and look inside. While you're at it, you can take some additional pics of the case innards.

Can you suggest some Fans 120mm and 140mm and budget friendly Cases so ı can save them and buy when the time comes

Since choosing a PC case is personal choice, go with the one that you like the most. Though, do note that cases with solid front panel (e.g NZXT H500) have considerable handicap in frontal airflow, which you can negate with high static pressure fans but which in turn also increase the noise coming from PC.

But for good airflow case at cheap price, Fractal Design Focus G is one of the best ones (i like it also because it looks like a miniature version of my Corsair 760T V2 Black case), and it comes in several color themes,
specs: https://www.fractal-design.com/home/product/cases/focus-series/focus-g
pcpp: https://pcpartpicker.com/products/compare/ZHmxFT,YhzZxr,ZKCrxr,Yzbkcf/

And for additional fans, 140mm Arctic F14 PWM PST fans have very good value,

pcpp: https://pcpartpicker.com/product/bkZFf7/arctic-f14-pwm-pst-74-cfm-140mm-fan-acfan00079a

Same goes with 120mm Arctic F12 PWM PST fans (i've had several of those fans in use for good cooling with low noise and at cheap price),
specs: https://www.arctic.ac/eu_en/f12-pwm-pst.html
pcpp: https://pcpartpicker.com/product/Kpprxr/arctic-f12-pwm-pst-530-cfm-120mm-fan-afaco-120p0-gba01

If you'd go with Focus G case, i'd buy 4x 140mm Arctic fans and mount them as follows:
Front - 2x 140mm Arctic F14 fans as intake
Bottom - 1x 120mm stock fan (or Arctic F12) as intake
Rear - 1x 120mm stock fan (or Arctic F12) as exhaust
Top - 2x 140mm Arctic F14 fans as exhaust

With this, you'd have 2x 140mm and 1x 120mm fans as intake and same sized fans as exhaust, giving you neutral pressure, which, when needed you can easily tune towards positive pressure (when running intake fans faster than exhaust fans) or negative pressure (when running exhaust fans faster than intake fans).

Thank you very much man

get a better cpu cooler replace it and problem solved. a new case with better airflow would help but changing the cpu cooler to a better one would do the job.

By the way this might sound a bit stupid but how does the Bottom intake fan work since there is no room for the air to go through under the case and are all my components going to fit in that Focus G specially with all those fans and are there any powerful cpu fans that you would suggest ?

Cases with bottom mounted PSU and with bottom mounted intake fan have high legs that give enough space under the PC for the bottom intake to work. For example, under the spoiler is side view of my 760T V2 Black case where i have bottom mounted PSU and bottom intake fan installed as well. Just look how high my PC stands from the ground,

Spoiler: 760T v2

And yes, you can fit 4x 140mm and 2x 120mm fans into Focus G case since it supports so many fans at once (read the case specs link i gave above).

Focus G has CPU cooler clearance up to 165mm, meaning that you can even fit some big-sized CPU coolers in there, like Be Quiet! Dark Rock Pro 3 (at 163mm tall) (pcpp). Though, Dark Rock Pro 3 will be way overkill for your non-K CPU and it also costs quite a bit. Here, i'd go with medium-sized CPU cooler, like Arctic Freezer 34 (157mm tall),

In my Skylake build, i have the predecessor of Freezer 34 in use, known as Freezer i32. My CPU idles around 26°C while most what i've seen out of it is 55°C during CinebenchR15.

Will that Cpu cooler fit in my case and does that cooler go with İ5 3570?

 

[Aeacus]

As i said above, i wasn't able to identify your current case and without that, i can't look up it's specs and CPU cooler clearance. Though, you can measure the available space in your current PC case to know the range of CPU coolers that fit in it.

i5-3570 uses LGA1155 socket and both the Dark Rock Pro 3 and Freezer 34 support LGA1155 socket. Also, both fit into Focus G case just fine.

 

[tsnor]

FWIW, before replacing anything, check the BIOS CPU fan setting. Set it to 100%, NOT to controlled. For my i5-3570K the default fan setting tried to keep the cpu at 80. Going to full speed on the CPU fan did not make any more noise (good case) but did cut the temp quite a bit.
