Additional CPU socket cooling?

Basically, just as the title says. I have an FX 8320 cooled by a Corsair H60 (The rig in my signature). I have managed to get this CPU up to 4200 MhZ @ 1.272 V, as reported by CPU-Z. This is stable under Prime 95 stress testing.

Now, when I monitor the temps in HW monitor, the core temps, which appear as "Package" temps run at about 48 degrees C max under full load. Ambient in room is about 18-20 degrees C. But the socket temp is a different story. It will run up to about 68 degrees C. The measured motherboard temp never exceeds 30 degrees C. I have seen before that AMD states max for FX CPU's is 70 on the socket. I can't help but think this temperature difference is due to the lack of focused air flow over the socket and north bridge area of the motherboard. There is plenty of airflow in the case. I have 2 140mm top mounted exhaust fans, the H60 set up as intake, and 2 120mm front intake fans.

Is there any suck thing as a fan set up that can blow air over the motherboard CPU socket area? or would this be a custom jury rigged sort of job. And if so, has anybody set something up like this that could post pictures and/or details on how they did it and what they did? Also, would turning the radiator fan around so it exhausts hot air out be a better option than having it intake air into the case? or possibly push pull fans on the radiator exhausting air out? Any tips are greatly appreciated as I do not feel comfortable allowing that socket temp to go above 70 degrees C, and am basically locked at 4200 Mhz to keep it below that. at 4300 I had to bump up the voltage an increment for stability, and it would hit 72 degrees on socket then.

In general when your water-cooling you want to make sure theres sufficient airflow over the socket itself. Motherboards are designed to use the incidental airflow from the stock cooler to deal with the VRM's and such, so even changing to a tower-style heatsink can impact that.
I have an old 80mm fan zip tied to some tubing and the rear fan mount, pointed at the socket to provide that airflow.

You want the radiator exhausting air, no reason to dump that heat into the case as everything else will suffer. That, and the rad is on the top panel, its pushing hot air down, which as you can imagine isnt the most efficient way of doing things.

Hello and thank you for the quick reply! So, you're saying turning the radiator fan around should help out some? I suppose I will try that and see if that helps out. If not, I suppose the extra fan tied in there should. Would one of those RAM cooling fan kits help at all since they blow air down on the RAM and are set close to the socket area? I have searched high and low and apparently nobody makes a kit of any kind for adding additional cooling to the socket area:(

Turning the rad fans around wont help much for this particular issue, but I think its just better to have the radiator exhaust that heat than drag it into the case.

RAM cooling kits, dont know, but I dont it will help help as typically heatsinks and such are located more toward the IO and above the socket.

The Antec Spot-Cool is the closest I can can think of to a packaged solution to this problem.

Ok, I turned the radiator fan around so it exhausts hot air now. Ran Prime for about 10 min. Motherboard temp went down 1 degree C, core temps were 1 degree higher, and socket temps topped out at 68 degrees C, same as before. So it helped the motherboard reading, but still that socket gets really hot. I did notice when I was dialing in my OC, that when I had the D VRM CPU load line set to high instead of very high, the socket temps were lower, but then I had to up the voltage to about 1.312 I think it was, but then my voltages were all over the place and it would under volt when running Prime causing a worker to stop about 10 min in. So I went in and set it to very high, and then dialed to voltage down as far as I could incrementally, which kept the temps below 70, but caused me to be stuck at 4200 with my current voltage. I'm not really sure if my settings are causing issues with my temps, or if it's just a lack of proper airflow over the socket.

That spot cool thing looks like it could possibly help a bit though. Really a shame more companies don't make such products. After extensive googling, I found multitudes of threads asking about solutions for additional socket area cooling. And yet, there was next to no solutions aside from jury rigging to fix issues such as this.

Well, solved part of the problem. I somehow overlooked my bios version when setting up my system. I was running an out dated version. Flashed to the newest version, and temps are reported more stably. Before, they would climb very quickly and fluctuate. My socket still hits 70 degrees @ 4.2 Ghz, but after about 45 min of prime blend tests instead of 4 min, So I feel alot more comfortable about running that clock. I am probably just going to order some small case fans and position 1 or 2 of them near the socket. Can't really thing of anything else to do. I have an 80 mm CPU fan there now, but it is very old and makes funny noises.

But, to anybody reading this, if you are getting strange temp reading on an Asus m5a99fx pro r2.0, check the bios version. I must have looked at it 10 times and still didn't notice that it was out dated. Guess there's always something us new builders will forget to check.
