need some help with my configuration of fans

[sbocky]

hey guys, i need your help with something, im looking for a good airflow in my pc but i am struggling with that.

 

In my h440 case, i have a rear 140mm intake, 3 120mm intake in the front, a 240mm rad on the top with the fans outtake. Also I have the 980ti strix with 3 fans, which produce some innerheat too. Soo my question is, what should i change to improve my temps in my case?

[JebKerman]

potentially, turning the rear fan around might help, but it seems to be in the best you can get, the H440 is not really air flow optimized.

hmmm, so rear needs to outtake, and the fans on the top, what should i do with those, should i let them intake and built up dust in my rad, or should i let them outtake so they dont built up dust but they will let warm air go through the rad

[blackadder]

Leave it as it is, i would of set my up the same way. If you have ample free time change them around, you are in the best position to test it.

Generally it's:

Front = Intake

Top = Exhaust

Bottom = Intake

Rear = Exhaust (but in some cases will be better as intake)

The only problem is, is that my cpu is running 40-45c in idle. Also, when my gpu is under load at 80-83c, the fans on top drag that warmed up air through the rad

that is pretty hot. What cpu? On my phone so i can't see member stuff below their name, if not a 200 watt beast, remount you cpu cooler. I don't have a 980ti but that also seems high,it may be the fan speed it to low. H440 doesn't have the best airflow. Take the side panel off do temps decrease by 5c or more if so get fans with better static pressure to get cool air from the front or leave the panel off, lots of people do it.

i5 4690k @4.6GHz, the thing is, Yesterday my cpu idle temps were like 30-35c, now that i replaced my 770 with a 980ti strix, the temps moved to 40-45

just added alot of heat to the case. Better fans might be the best option, do test with panel off first. Getting the hot air out is the biggest priority. That still is a big jump, does you cpu cooler feelhot to the touch, gpu will don't touch it. Also when grabing something hot reach with the back of your hand, if it is hot you will flinch and grab onto it

you learned it the hard way?

cpu block doesnt feel warm, just gonna let the temps go down now. The rad isnt feeling hot either. Something is not right, because they dont feel like 40c. gpu temps moved 1c and the cpu didnt move, maybe 1 degree too.

[JebKerman]

it'll also be exhausting anywhere it can, air flow is fine.

That 770 didn't happen to be a reference or Blower design? If so that would explain it, as blowers dump less of their own heat into the case.

nope, it was a msi oc

 

@blackadder , cpu is getting down a bit slow, like its 40c and sometimes dropping to 38 and then really quickly to 40 again. the gpu temps didnt move, but the fans started to run 100rpm less.

that is strange, the cpu block wobt be hot, you are getting reading from the cpu cores that amount of heat won't raise the metals temp that much, a gpu can and will. I would remount the cooler. Gpu im less worried about they are happy at 90c, cpu is 100c. So you still are in the clear for temps but it is strange none the less. Compare other 980ti strix temps to see if yours is being crazy. Also your rear most fast should be exhaust like the rads.

i will fix the 140mm rear in a few ours, dont wanna wake up my mom and sis. Also i looked up a review on guru3d about the strix, at idle they said the temps were 50 degrees, well mine is 60 unless i put the fans on 100% and then i would reach 50c. Same as the rearfan, i will remount the cooler. But can you explain the sudden rise in idle temps of the cpu, seems pretty weird to me.

they will jump like that, heat transfers very quickly in a small space. I use msi afterburner for cpu temps, my mb software is a little off, also did the temp in your room incease (alot) that would bring idil temps up. Lastly what is voltage of cpu, not to high 4.6 is a good oc, its not that high because volatge is 1.3v? And the volts go down with clock speed? Mine is @4.4 with 1.17v idle is 32c with 74c hottest core folding proteins.

i honestly can't. You did add about 300 watts of heat into your case at full load, that a good bit of extra heat but, why is it that high at idle when there is almost no extra heat does worry me.

realtemp gives a max of 54c idle on cpu?!!?! and an average of about 41. I dont have an indication of my roomtemp, but i guess its around 20c, i cant feel the tempdifference with my skin, or its the alcohol . My cpu is clocked at 4.6 with 1.28V. the Volts go down with the clockspeed indeed.

[sbocky]

@blackadder , something which is weird too, is that when i increase my fanspeed of the fans on the rad, they will increase the temps.

 

nvm, the average got down a bit with 3-4c

 

nvm, its looking around 35c now which is pretty ok i guess

but every fan is working at full speed, which annoys me

 

cpu temps average are around 32c now

 

 

 

the thing is, is that i had the rpm of the fans really really low until the temps hit 60c, for noise reasons. Is it bad for the cpu to run at 50c idle?

those are good volts.. .888v is what i get a idle, this is strange. Head to the Winchester have a pint and wait for things to blow over? Im all out of ideas. You won't damage anything atleast or you are not as long as load temps are decent. What are they? Below 80c for cpu and 85c for gpu.

ahh, great thats good, means you lack airflow in that area i would guess. 3-5c is the best i tell people temps will decrease with crap to good fans. So run fans higher or get ones with more static pressure over 1mm hg

ill do a quick stress test. Atm im drinking some johnnie walker double black, solid taste for not that expensive scotch.

atm on the rad, i use the standard fans, swiftech helix. But i hate this noise :1

@blackadder , update: 100%fanspeed, average 28-30c

@blackadder , holy macaroni, this is amazing, my temps on aida on load arent exceeding 60c!(well there are some minor twitches to 65) so lets says average around 63

much better, i love me some gin, New Amsterdam to be exact. 50c isno problem at idle you do want some air to move across the mb to cool vrm and other junk.

Ill fix that in a few hours by making the rearfan outtake.  Btw do you have a good advice for some kind of scotch or cognac? Im 18 and still have to expand my horizon of good booze(dont  drink for the feeling, just taste) Ill try that gin of yours

not off the top of my head. Stay away from any bottle you can squeeze, or anything that says miltary special. And to the question about burning yourself, no i was taught it but i did shock myself where i couldn't let go for a few seconds caused a small patch of blood vessels to suface like welts almost.

thanks for the info.

btw ive send asus a mail to their techsupport about the crazy high temps on gpu. Ill keep you updated..... and I will get that gin today!

 

ps I hope that asus sees the serial number of my gpu and says that that gpu should have been recalled.(there was a defect with the heatpipes)

[sbocky]

@blackadder 3dmark, my temps with default rog fancruve were about 76 degrees, my temps with 100% fans was max 63c. Also ive put my sidepanel on and made the rear outtake. I think it works as it should be. Btw, idle temps normal fancurve is 50-60c, with 100% fans 36c.

 

furmark, normal fancurve, 83c,   100%fans, 67c

is this ok?

yes, these look very good, much better. Now to find the highest rpm you can stand and that should give you a good noise to temp ratio
