Fan Placement in case

Andrew Buck · May 10, 2014

I have a Cooler Master HAF 912, and want to put in some of my old Rosewill fans from my old case on top to get better cooling in the socket and VRM. I have every spot used in my case except for the top 2 slots. Specs:

Case: Cooler Master HAF 912
CPU: AMD FX-8320 @ 4.6 GHz (1.4V)
Motherboard: ASUS M5A99X EVO R2.0
GPU: MSI Radeon R9 270X Twin Frozr 2G
PSU: Corsair CX750
CPU Cooler: Corsair H60 Hydro Series

I have this setup, but do not know if it is stable. My temperature on the socket gets above 70 C (maximum recommended) to around 72 C after about 3 minutes of Prime95, so I always shut it off to prevent damage. I have 2 fans from my old case that I have places for (on the top, there are 2 slots open). The front fan is taken by a stock case fan, the exhaust is the stock case fan, and the case door fan is the H60's fan pulling air out of the case, due to the large GPU blocking the tubing from going anywhere else. I have 2 spots on the top of the case for fans, and I have 2 fans, one that can connect to the PSU with the 4-Pin MOLEX connector, and 1 free slot on my motherboard for a fan. I am debating on the direction of the airflow, whether it be into the case to run across the heatinks, or a second or third exhaust fan. Would this also help my socket's temperature when on load? The voltage probably isn't enough, but I have no ability to test its stability. Thank you, and any help is greatly appreciated.

Hi I have a 912 HAF case. I have a 200mm front intake fan, the stock 120mm rear fan for exhaust and two 120mm Fans in the top for exhaust. That gives me good air flow. As for that H60 cooler, you would do just as well with a Coolermaster Hyper 212 EVO air Cooler.

The cooler is not what I am looking to replace. I am just trying to figure out whether or not making them intakes would help with blowing across the heatsinks.

I know. I just added that. Put a good 200mm Fan in front and you will have enough.

Alright. Will this help me with socket temps vs the stock fan? Also, are there any that you recommend?

I have absolutely no problems with temps, even when the ambient room temp goes up. Things will get a bit warmer, but not overly so. Maybe 5c degrees. I am using aircooling on my CPU ( 4770k ) and have it OC'd to 4.6 Ghz and the temps are fine. I have very good air flow through that thing. As for fans, I am using Cooler Master fans. You want to pay attention to the CFM numbers of the size fan you are looking for. The higher the better.

If things get warmer, then why would I change to it?

You change to it to keep it cooler than it would normally be. It IS normal for your temps to be a bit higher if the ambient room temp gets higher. You are pulling in warmer air to cool things. It can get into the 80's in this corner, but my temps do not go up more than 5c ( upper 30's to maybe low 40's ) under normal load I have never seen a CPU temp in the 50's, even under load and I am using air cooling.

Oh, you are talking about the ambient temperatures. Yes, they may go up 2-3 C as summer progresses in the near future, but will the 200mm fan be helpful to the socket temps? Also, what is a good fan?

It is helpful in establishing good airflow through the case and as long as you have that, you will stay cool. That is my proimary concern when working inside my case for the first time. Try to keep it as uncluttered as possible even down to using a ful modualr PSU to keep the cable count down. Cable / wire management is helpful. What you are looking for is First, the size of fann(s) you want and if you want LEDs. Second and probably the most important, look for fans in your selected category with the highest CFM rating. The higher the rating, the more air that they will push / pull.

I am aware of all of this and have all of my extra PSU cables tucked away, but my watercooler and GPU somewhat block airflow.

The GPU shouldn't be an issue. I don't know where your radiator is, but if you have a good Intake fan or two 120mm's plus two good exhaust fans up top, then you should be fine. The room temp is about 77 degrees and my CPU temp is in the low to mid 30's ( I am OC'd to 4.6 Ghz ). The MOBO is at 28c. The airflow temp is about 31c ( GPU 40c ). All good. Probably need to go inside there and do some cleaning, but have been busy. Lost My Mom to Lung Cancer in Feb. and things have really been in a mess around here.

The GPU isn't giving of heat, it is just huge. Back to the original topic, should I put my fans as exhaust on top?

That is the way I have them ( two 120mms ). I have a GTX 680 in here and that is no small card.

Alright, thanks. Does the Cooler Master Megaflow 200mm sound good?

That's a good one. 110 CFM is a good rating. I think it may be the same one I have in here, but mine has blue LEDs.

Yes, that is the one I am looking at. Thank you. One more thing - is there a possibility of cooling the socket?

When you gert your Motherboard temp in the BiOS that is where it is being measured. I have never seen that get overly warm, even when the CPU was warmer than it should be.

I monitor this, and while gaming and Prime95 with an overclock over about 4.2 GHz, it gets to 75 C then throttles. This is not the core, as that gets to only 50-55 C on load. On stock speeds it even gets to around 60 C on the socket and 40 C on the core. Idling on 4.4 GHz @ 1.4V is 43-48 C.

The only way to effectively cool that area is by establishing good airflow. It can be done with a HAF ( High Air Flow ) case. I'm wondering if you are looking at the socket or maybe a chipset. My other desktop ( Intel Socket 1366 ) had an issue with the Northbridge. That thing got toasty ( too much so ). I eventually found a fan that I could attach to the heatsink over that thing.

Andrew Buck · May 11, 2014

The chipset sits at around 33-35 C as I have found. Here is a screenshot of my temperatures as of now at stock speeds:

Oh, I know that is a bug, I forgot to write that. This board doesn't show the correct temperature there, nor does the M5A99FX or Sabretooth 990FX, etc. I am talking about the highlighted temps.

coastie65 · May 11, 2014

Andrew Buck :

The highlighted temps are fine as are the rest. It was just the TMPIN2 reading that was off.

Andrew Buck · May 11, 2014

coastie65 :

Max temperatures after 15 minutes of Prime95

Temps after just 10 minutes:

As you can see, the socket temp is HOT. I need a way to cool it down. I installed 2 75 CFM exhaust fans on top, too.
