Suggested air flow?

[Dyroo]

I have this case where i removed the side panel because it heated even more the CPU (even while having air); It only has a PSU fan on the back, a fan on the gpu, a fan on the cpu, and a fan on the side case (which i removed, cuz it didn't work).

 

I'm wondering how should i position the CPU fan exactly, because i'm noticing that even while running at full speed, and my hand literally a cm away, it doesn't seem like blowing out that much air at all, but more like a small breeze, and i noticed that it pulls it inwards.

 

It's a stock cooler from the cpu, and it's an AMD one (the socket is rather old since my MB is an M2N68-AM SE2, so any new fans won't work here); It has a 4 pin connector (even tho it has 3 cables in 3 pins for some weird reason).

 

Thanks for answering.

You need some case fans, you need some way of getting fresh air in and hot air out. I would start by replacing the fan you removed, and maybe look and see if there are any unused fan mounting spots on the case and get another fan or 2 to increase airflow.

 

Most stock cpu fans don't move a ton of air they are just there to create airflow over the cpu heat sink.

well you probably arent feeling any air on the cpu cooler because its not blowing out air. its sucking IN air and blowing it down on the heatsink and motherboard.

 

and yes you need case fans, at least one of the rear to exhaust heat out of the case. 

more intakes than exhaust is the general formula that will help keep your pc cool and stay dust free (relatively)

Only if the intakes are filtered.  Anyway make sure you clean any dust away with compressed air and make sure you have at the very least 1 good exhaust fan as close to the top of the case as possible (thermodynamics may only have a small effect inside a case but don't fight it if you don't have to) but I found having at least an intake and an exhaust provides a better cooling effect for not much money

[Mooshi]

Ideally you want a front to back set up with front intakes and a tower cooler sucking in that air under air cooling. If your case lacks front intakes, you can opt for using a top fan slot for intake vs exhaust. For some perspective, here are my temps in a Fractal Core 500 with no front intake, a top 140mm Venturi acting as intake and the stock exhaust fan.

 

 

Used to have a Define R4 with my old build and frankly, side fans are pretty useless.

they are very helpful if you can't find another way to get fresh air under the gpu, but otherwise you're right they don't help a lot

[LogicalDrm]

Pics & temps please. Also, case fans do very little when you have open side panel. If you keep it like that and want more fresh air, you need to position extra fans to blow directly towards hotter components.

Your hand is not an accurate tool for measuring airflow--look at your temps instead. 

What are your specs?

I heard that the core temperature is not the temp that matters, it's the MB one, because apparently the core temperatures are +10ºc higher, according to a website.

 

Is this true?

 

Also, i deattached the side-panel fan and attached it instead as a fan BEHIND the computer so it could suck out the hot air.

 

Here in Argentina, i'm on half spring and entering summer next month, and today for example is doing 27ºc (at least the weather thing says that, it's heavily hot in here).

 

Thanks for answering.

 

EDIT: GPU Fan says 0% but because it's a wrong reading, the fan is spinning as usual, and the gpu reaches 60ºc max on heavy loading

What case do you have and how is your cooling laid out?

Are your motherboard settings set to default?

All temperatures matter--just keep in mind that they aren't the same reading and that what's safe is different for each of them.

Yes, core temps tend to be higher and the socket temp is usually used to extrapolate the core temp in AMD's case.

I got a cooler on the PSU, a mini-cooler on my GeForce 8400 GS (it's really just a mini-cooler by default, can't do anything about that), a fan on the back of the PC just alongside the CPU to suck out hot air, and the cpu fan.

 

I also have a Sentey case EXACTLY like this one (http://www.pc-specs.com/case/Sentey/Sentey_CS1-1398_PLUS/1383): 

Except without the side panel, since i took the fan out and placed in the square at the back of the computer as you can see there.

 

I don't know if my motherboard is set to default to be honest, because i was always too afraid of fiddling with any of that, and also my brother used to do all the settings back in the day.

What was the reason for moving the fan? Did you pay attention to any change in temps?

I moved the fan because i noticed my computer gathering more heat on the CPU (as the pic above shows the temps), and i thought it maybe could need an air exhaustion so it could remove the hot air a little bit.

 

And...to be honest, i think it only made a 1 or 3ºc of difference, or probably none at all.

Were the temps from before the fan was moved? From what I'm seeing, a side pane intake would probably be better for cooling. That being said, an extra fan for either slot would be even better.

It's the same temperature; The thing i noticed is that the temperature when i'm running any game, or the CPU reaches 100% usage, both core temperatures can go 10ºc higher in a second, and then escalating until reaching 71 or 74ºc if it's cold, or 85ºc if it's pretty hot outside.

Can you try using CoreTemp instead and seeing what results you get from that? http://www.alcpu.com/CoreTemp/

Alright, so after counting down with a timer how much i've spent in the game while getting these readings, after 45 to 50 minutes of playing Sven Coop (a HL mod), the results were...the same:

 

Also notice that the temp room is around 24ºc (looking at the weather thingy here) in my city, and is the maximum temperature registered so far in the system.

 

CPU Load was from 96% to 100% the entire time i was in the game, and the game in particular looks like this, at 1024x768 resolution:

And these are the current temperatures at idle:

The configuration of what you have probably isn't the issue.

It could be the thermal paste, cooler being inadequate, or lack of case airflow. 

You could try reseating the cooler and check if the thermal paste was properly applied. Your best option is probably to replace the cooler though.

I re-applied the thermal paste a month ago, and i don't know how is that "reseating" thing on the cooler.

 

The cooler is functioning as intended since i first got the computer (it's spinning at 3k rpm) 7 years ago.
