Not happy with Coolermaster 212+ Evo

[railven]

Perhaps, I don't have enough fans on the 212+ or perhaps I'm expecting too much.

System:
Corsair Carbide 500r
2x120 Intake - front
1x140 intake - side
2x120 intake - top
1x120 exhaust - rear
(I'm open to suggestions if my fan layout is poor, I've been think about inverting the chimney fans.)

Corsair 750w TX PSU
Sapph Radeon 7970 + Accelero Extreme (love the temps here, no issues)
Intel Core i5 2500k
Cooler Master 212+ Evo
1x120fan (stock) drawing air from front (above ram) to rear (lined up with exhaust fan.)
The two chimney fans blow right over the 212+ Evo.


Maybe my temps are fine:
Stock: ~33c idle / ~45c load
4.6ghz OC @ 1.3v [note: aware this might be too high]: ~35c idle / ~55c load
[All temps -/+ 2-3c]

Due to where the PC is, the room's temp vary (a lot) from ambient in the ~75f (~23c) to the 85f (~30c), and when the room escalates to the higher temps, the load for OC settings can hit 60c+ easily.

I've tried resitting the 212+, I use AC5, the GPU doesn't experience such varying temp changes even stress testing it at 1265/1700 @ 2.74v the GPU never broke 60c.

Anyone got any suggestion, or am I just being paranoid and trying to give myself a reason to buy a more *expensive* Heatsink? Would the second 212+ fan really make that much of a difference?

When you say load what do you mean?

Run intel burn test on "very high" and set "times to run" to 10 and post here with the temps can you also mention which software is giving you the temperature measurements.

Also on a side note (and I see this happening a lot on these forums) could you stick to one measurement i.e °C or °F in your post it is very confusing for anyone who doesn't use both on a regular basis.

55 Degrees for 1.3v isn't bad at all. Not sure what the issue is?

The 212+ isn't really ideal for going over 4.5GHz unless you have a great chip.

 

[railven]

By load I mean Prime95, which task manager pegs all 4 cores at 100% *load*

The thermometer in the room reads in farenheit, but I guess I can convert to celcius. Will update the post with adjusted temps for ambient room.

From what I've read on these forums, for my ambient temps the load temps on stock seemed too high for me.

The OC is done using the auto OC on my ASRock Z68 board, when I set the OC'er to 4.3 the temps are about the same with volts in the 1.22 range.

Again, like my post said - not sure if I'm just being paranoid on the temps.

 

[p_monks33]

The auto overclock feature isn't the best way to go about overclocking. I would say that your load temps are really good. 55-60 degree load is ideal. 80+ is when I raise my suspicion that something is wrong.

 

[Binky]

Temps look good to me.

Can you pick out posts you're referring to? Not everyone who posts with an overclock and temp report is to be believed.

I think any knowledgeable person would say your temps are fine. (And really, since the 212 can run your desired overclock at perfectly safe temps, who cares what the exact numbers are?)

 

[jacktesterson]

I can tell you I had a 212+ on my current HTPC rig before moving to the HTPC case, and my temps were a little better than yours at 1.3v, I was using a Corsair 500R case. I got your temps at 1.35v, but I was also using a Push/Pull configuration. Did you add a 2nd fan?

Either way, your temps are fine. You have a long way to go yet before being concerned. (I like to stay under 70)

Only went to the Noctua as 1) Smaller case 2) High end air performance 3) lower profile . It was $80 though.

The $25 212+ remains the best bang for buck for most.

 

[Kenmitch]

Change the top fans to exhaust it'll help temps and is better for spills also.

 

[jacktesterson]

Good catch. That top fan should definitely be exhaust in my opinion.

 

[Puppies04]

Your temps seem fine, you will also have some headroom to overclock manually and lower the voltage from where it is at right now as the auto overclocks tend to add too much voltage.

I really wouldn't worry about your idle temps, taking your lowest ambient your CPU is sitting 12°c hotter which as a worst case scenario really isn't bad at all considering your CPU fan/case fans should be running at minimum at this point.

I would go as far as saying your numbers aren't just "ok" they are actually quite good.

 

[railven]

Thanks for the info, I guess I am being paranoid about the temps.

I'll reverse the top fans and then work on a manual OC, the auto-OC was just me testing the temps since I know high volts are often used to get high clocks. The highest the auto OC'er got to 4.8ghz and the temps were 65c+.

I'll work on the rig, fix the fans, and then setup a manual OC.

Thanks for the feedback.

Hello,

I finally got some time to do some manual benching, here are the settings as I recall them:

Turbo Boost Offset +0.004v
Core Offset +0.005v
44x Multiplier
C1E: ON/C2:Off/C6:Off/C-Package:Off

RAM
1600mhz 9-9-9-24-1N @1.5v

I went for a simple OC, aiming for 4.6ghz but my temps are still worrying.

That was 1 hour of Prime95 with those settings. I couldn't get the system stable at 45 or 46 multiplier with Turbo Boost Offset to 0.016v+ Will work on that later.

Am I still being paranoid about my temps?

EDIT: I didn't take a capture during the torture testing, just using the Max values recorded as my reason for concern. Temps were normally between 68-78 C, ambient temps were in the ~26C

 

[tinmann]

I really don't see reason for concern. Those temps at those clocks seem nominal. If you want better temps you might have to consider water cooling, but with a Corsair H100 on a i5 2500K overclocked @ 4.327 running Prime 95 I was getting similar temps as you are now, that's why I went to a custom loop.

 

[MontyAC]

Your load temps are fine for the 212+. I get close to 70c when I do video encoding.

 

[rickon66]

Your temps look pretty good to me, but if you have been running your top fans blowing in you are probably causing some heat retention inside the case. Of course heat rises and you need the top fans blowing out to get rid of the hottest air. As others have said add a second fan to the cooler. I have both the 212+ and the EVo and have been happy with them.

 

[blastingcap]

One of my cases is a 500R which I fixed by making my own mesh filters for the side intakes. Your temperatures look normal-ish. You didn't list the specs of the fans themselves which is kind of important.

If you want to drop temps more, read this thread. http://www.overclock.net/t/1037539/intake-fan-in-a-5-25-bay-warning-graphics/0_100

If you continue to read OCN's air cooling forum in the pursuit of lower temperatures, you will probably end up ditching the top fans altogether and seal them up, followed by installing a 120 or 140mm fan in the top three 5.25 bays, followed by cutting out the rear grill and removing the rear fan. If that's still not enough for you, get a second fan for push-pull. Still not enough? Make a shroud for them.

OMFG YOU HAVE HORRIBLE TEMPERATURES.

Oh wait, you don't. They look fine to me. :sneaky:

We must be reading different forums.

I'd do this too. Your case airflow is unbalanced. Not sure if it would make a huge difference in temperatures, but you should flip the fans nevertheless.

Hot air rises, sure, in a closed, static environment, and then by convection.

But once you add in active air movement, such as a fan pushing 32cfm, you can certainly make hot air sink, as you're actively pushing the air down.

True, it's easier to vent the hot air up and out, but that's certainly not the only viable solution for expelling the hot air created in a case.

 

[Phil L]

Someone correct me if I'm wrong, but I believe the CPU diode sensor is also not very well calibrated no? I.e. while it is accurate on relative increase/decrease in temperature, there can also be a systematic error up to a couple degree C reported (e.g. true temp 30 may be reported as 35, true temp 40 would then be reported as 45, and so on).

Anyhow, I don't really understand why people obsess over a few degrees (especially in light of calibration error margin), when they are far far below the stock operating temp and safety limit even when OC'd. I can understand if you are pushing your SB/IB in the 90s pursuing max OC, but otherwise... Maybe it's just me.

The problem is not that the top fans are set for intake.

The problem is that there are five intake fans and only one exhaust.

This is the internet. We all have the right to be entertained, outraged and obsessive/compulsive.

Check the Memory and Storage forum for the lulz to see all kinds of SSD benchmarks and crying over perceived low performance.

Yup. With so much intake, that exhaust fan is pretty much just getting in the way -- the hot air is going to go out due to positive pressure anyway.

Yea I noticed that also.

Some prefer Pos pressure to eliminate dust around connectors, some like Neg pressure as supposed to pull heat better.

I myself try to pump out the same as I pump in. But that seems to keep the air flowing the best for me. But each their own.
