Reddit reviews Enzotech Mosfet Passive Heat Sink, 6.5 x 6.5 x 12 mm, Copper, 10-Pack

Of the motherboards you list, the DS3P and Extreme3 would probably be the better overclockers, but the ASUS is probably a bit more reliable. Both the DS3P and Extreme3 have a sizable portion of questionable reviews on newegg which makes me hesitant to suggest them. I guess if you want to stick with the LE that works but it will slightly limit your overclcoking ability, but this could be remedied by buying MOSFET heatsinks at a later date (like these )

As far as the RAM goes, literally get the cheapest you can. CAS/mhz isn't all that important as far as performance goes. Even dual channel doesn't matter that much.

For the monitor, the ACER seems like the best choice. It uses a VA panel which is like IPS, so its got slightly better picture quality than the rest which uses a standard TN panel.

TL;DR at end

What helped me out a TON was undervolting. It's the exact opposite of overvolting (duh). It lowered my CPU socket temp from like 62 Celsius to 45 Celsius under load (with a gelid solutions tranquillo rev 2). It's really easy to do, go into your BIOS and lower your voltage in small-ish steps. Undervolting cannot harm your CPU, the worst that can happen is thats your PC crashes. To test if your undervolt is stable, use prime95 small FFTs. Also use hwmonitor or windows ttask manager to track CPU usage. Without undervolting you will probably see severe dips in usage% or in clockspeeds because your CPU is being throttled because your VRMs are too hot (or your CPU is too hot, but in your case its more likely to be VRMs). After undervolting quite a bit, while testing with prime95 again those dips should not be returning. However, undervolting too much can cause some instability and some cores can shut down while using prime95, so do keep an eye out for cores that stopped working using prime95 after you undervolted. You can see a core stopped working if its usage is not 100% anymore in HWmonitor or just read for errors in prime95, it should say "worker stopped" or something along those lines.

How much you can undervolt differs per chip, I was able to reach 1.125Volt stable with an FX 8320 on 3.5 GHz.

You might also want to look into buying VRM(read: MOSFET) heatsinks.

These can work http://m.ebay.com/itm/321204413195

Otherwise these (bit more expensive) https://www.amazon.com/Enzotech-MOS-C1-MOSFET-Heatsinks-Pack/dp/B004CLDIHK


Last resort is to disable 2 cores on your FX 6300 as well as undervolting, you'd get less performance but at least there's no throttling anymore.

Sorry for wall of text,

here is tl;Dr

1. Undervolt!
   
2. Buy cheap vrm heatsinks
   
3. Disable 2 cores (last resort if throttling is not solved after undervolt)

What I did was remove the heatsinks on the z370i and replace them with some VRM heatsinks I found elsewhere. That allowed me to mount my cooler with its fins parallel to the ram and drastically reduced temperatures in the case. I used these, but they don't appear to be in stock with amazon anymore.

I got these ones. The original heatsinks are attached by 2 screws each on the bottom of the board. You just unscrew those and they come off. The copper heatsinks come with thermal pads with plenty spare if they don't stick well enough.

How effective do you think these would do the job? https://www.amazon.com/Enzotech-MOS-C1-MOSFET-Heatsinks-Pack/dp/B004CLDIHK

The cheaper option would be to buy a new motherboard, one that is known to work with octocores:

However, if you can afford more I would suggest just jumping ship since putting money into a FX build at this point seems like a waste imo. This would require a new CPU, motherboard, and RAM and won't be cheap, $200-$300 roughly. You will get significantly better performance however.

A third cheaper option would be to buy some Mosfet heatsinks for your board, a side intake fan for your case, and undervolting/downclocking your CPU to get it stable on your board.

With respect to the comments about your VRM cooling needs, it's not difficult to make some gains in that area.

Apply them to your VRMs as illustrated here: http://www.overclockers.com/forums/attachment.php?attachmentid=134104&d=1382197078

You end up with something like this: http://images.hardwarecanucks.com/image/3oh6/evga/x58sli/small/heat-6.jpg

I think the EK-VGA Supremacy (copper or nickel, your choice) will do. The block can be oriented in any direction.

As for the VRAM and VRM chips it will be another story though... For the VRAM EK has Akasa AK-VMC01-BK VGA RAM Heatsinks (they don't need a whole lot of cooling, some cards don't even have any VRAM heatsink at all), and Enzotech has copper VRM heatsinks but you might need to cut them to size. Point a fan at them (the ones on the rads should be enough since they are close) and you are done.

If you're really worried about the vrm temperatures, it may be easier to attach your own mosfet heat sinks. Something like the ones linked at the bottom will be better than what all of the motherboard vendors use. The downside is that it won't match the theme of your motherboard.

These might work better to get the little ones in the corner near the io.

Easily solved with these lol(which I did on my crappy PRo m2 motherboard. Hey I bought the board for cheap for only 50 bucks open boxed!!):

But pricey, so might as well buy a better motherboard with good heatsinks haha

Maybe if you use thermal glue, but a penny doesn't have that much surface area, and I'm not sure how well it conducts heat.

It's better to get specialized heat sinks like these.

I'd be really tempted to wait till Monday and see what AMD's showing at Computex will tell us about their upcoming Ryzen 3 CPU's.

That aside, the 9700 (non K) should work in you mobo just fine, I'd probably put some mosfet heatsinks on the VRM just to be safe as the 9700 will be pushing that board to it's limit.

I put these on these on the gddr5 chips. I cleaned the adhesive off of them and used thermal pads to attach them.

I couldn't find low profile copper heatsinks small enough for the vrms on my 480 so I used these aluminum ones with some more thermal pads. Most small copper ones were tall, and I wasn't sure if it would fit together once the gpu cooler was attached .

If you're VRM are exposed along with your mem chips, I'd just go ahead and put something on them like this. You'll need to see if they are the correct sizes as I'm too le tired to do the research for you.

AMD user. Overclocked CPU to get more performance, got limited by motherboard VRM temperatures. Buying some of these to push it harder. Gonna be fun.
