Hmm, prices of the good stuff dropped a bit, compared to the last time I was shopping for these. Check these out:

http://www.frozencpu.com/products/17499/thr-181/Fujipoly_Ultra_Extreme_System_Builder_Thermal_Pad_-_60_x_50_x_05_-_Thermal_Conductivity_170_WmK.html

https://www.amazon.com/gp/offer-listing/B00MQ6AJU2/ref=dp_olp_0?ie=UTF8&condition=all

VRM can withstand the extreme heat in most cases. 990FX platform is known for its stock 140W CPUs, so even the crappiest engineer would beef up the VRM.

Your PC crashing may be not due to VRM overheating. I have a wild theory - VRM getting hot and no air circulation in that area means other mobo components are also getting pretty hot. Odd as it may seem, even a bad solder joint could be breaking contact if PCB or the copper traces expand whend heated. Other electrical components are also very sensitive to heat, resistors, capacitors, ICs - it may be the case where VRM are giving the poor surrounding elements more heat than the latter can handle. That alas is called bad design. Tougher components are more expensive.

Modern PC are extremely sophisticated electrical machines. Even the slightest electrical anomaly in their critical circuity (caused by heat in your case) will disturb the Zen of their inner workings, and ultimately lead to a hang/crash.

If interested - my Taichi's VRM are getting ~68C under stress. That's high for my non-OC CPU but it's because of the airflow I arranged (deliberately) in my chassis. I use Fractal Define G, my rear and top fans are SUCKING air (instead of blowing it out). Together with my front 2x140mm Noctuas (on CRSR h115i) blasting out I achieve good positive air pressure in the case, and good airflow as well. This setup however creates a whirlwinds over my VRM and it reduces their cooling.

As with everything in PC building, you're not upgrading, you're moving the bottleneck somewhere else! With good strips VRM can now transfer all their heat to the heatsink. If something, the bottleneck is now with the heatsink itself. Even some minor airflow should improve the situation now.




I can't really find anthing that shows as that expensive on google... and the website i found for their company didn't have any prices or words on the screen that i understood. I understand what you mean by i move the bottleneck around... i realized that when i started figuring out the VRM1 problem. By cramped, in my computer, i mean that there is cords and sh*t everywhere... i never had a problem with an open air case prior to this and it had never crossed my mind that i needed a case for proper air flow... but i picked up the Corsair Carbide Air 540 today and i am about to shut my computer down to do the transplant. so... I will let you know... I just don't understand why my computer hangs up at VRM1 getting to 86c if not for heat... I am also not sure on whether that is a setting or not that i can change...

Sorry, but that is pure BS. These strips are in essence, a TIM - thermal INTERFACE material, i.e. they combat the otherwise poor heat transfer of the air. If they terminate directly to the air, it's useless. They do zilch without a proper heatsink attached.

That's what I thought. But it litterally freezes up on GTA. And i can still see the screen with all my monitoring software going... and the only thing i see wrong is the VRM1 86+ Celsius. 

I think i may have figured out what my issue is though... I think that my case is just a clogged up mess of cables and stuff... i didn't know where the VRM1 was located, and after finding out where it was, i realized that my radiator was right above it. no wonder it was overheating... no airflow... and nowhere else to put the bulkey radiator. I was looking at other options online for cooling and a video about fridge cooling came up and i watched it and found out it was crap, then a video on air conditioner cases... that led me to another case called the Corsair Air 540.. http://www.frys.com/product/7733388

This thing is a beast... but it has good airflow for the monster card i have in my tower... and i can route my radiator to another location other than right over the top of my VRM1... will update after new case.

My 2 cents, you could also change the thermal pads or TIM of your VRMs.

Decent Fujipoly thermal pads with huge thermal conductivity will definitely drop the temps considerably. Only drawback is that decent thermal pads are very expensive. Like 50,- EUR for a single strip expensive.

yeah mine is a custom WC loop.  I might see if I can find a better way to mount some fans to give airflow across the motherboard.

The pads will definitely work (if they are not counterfeit, at leastLOL). And by work I mean they will quickly transfer the heat from the VRM to the heatsinks.

Running in an open chassis with a 'stale' air around the heated elements will always give you high temps, well, higher that usual at least. Problem is VRM and their heatsinks rely on the exhaust fan and air circulation to achieve optimal cooling. They were never engineered to run w/o fan in fist place.

Many water-cooling guys have stumbled upon this phenomenon. They ditch all fans from their PC chassis (it's cleaner and quieter, I give you that) only to see their VRM overheating.

Also, I too don't consider your VRM temps to be too high for prolonged use.

Hi Taynak I have heard of other people on the net having the VRM  problem and they all said my options were to get a small fan and connect it to the heatsink or a spot cool.  My system is in the Thermaltake core P5 completely open and my VRM1 still gets high temperatures.  Everything else stays nice and cool.  I like the idea of the Fujipoly thermal pads as zlobster said.  I ordered some so I hope they will work and if I am lucky ditch the Spot Cool.

Hello.

I am new here but this post was the closest thing i could find to my issue. I have the same board, the asrock 990fx Extreme 9 and a AMD 9590 vishera 8 core black processor.

I am also having this overheating of my VRM1 but I haven't done, nor would i care to, overclock anything on my computer. I am happy with the performance it gives.

The only things  different about my build is that it is in a opened up cooler master case and has a Corsair water cooler for the processor... the water cooler was required by the processor (at least thats what newegg said). anyway...

I currently have only one case fan, the one up front. all the others died at some point or another. but to augment, i have a small desk fan blowing down the top of the case vent and a box fan drawing air out.

I have also had the box fan turned around and blowing in but the VRM1 still goes above 80c. When it does, my processor locks up and i have to hit the reset button on the computer.

Now, i should mention that this all started rather recently, after i upgraded the graphics card. I installed a r9 290x. I had a GTX750, but it still froze up every so often, just not nearly as much.. and it seems to only happen when i am playing GTA-V.

I have my Corsair link programmed to set all fans (the cooler fans and the one front fan) to max in the event of an overheat anywhere on the board, AND i have MSI afterburner set to ramp the graphics card to 100% when it gets above 50c. This, combined with my box fan, should be more than enough to keep that VRM1 cool, but it doesn't seem to be wanting to work with me.

The only thing i can even possible think of is to pull the whole computer apart and see if the heatsink somehow came off and i need to re-apply thermal paste and reseat the heatsink...


Here is my DxDiag if it helps:
