parts for boosting amd fx 8350 to exceed 4.5 ghz
As mentioned in the title, I reached stable 4.5 ghz a few months ago, but due to power supply issues I had to revert. It was enough to realize I could handle it. However, things have changed now and I have some extra money, so I plan to upgrade my PSU first and then explore water cooling options for the CPU. I’ll also need a solution for cooling the MBO. Could you offer some recommendations?
Would your components still work at 4.5 ghz?
1. Which PSU would you recommend for long-term use, with a capacity of 1000W+, and now money isn’t a concern?
2. Should I go for water cooling or stick with Hyper 212 Evo? Also, could I use two R9 390s and install them?
3. If I opt for water cooling, what should I consider for MBO cooling?
Any advice or suggestions would be appreciated. Thanks in advance!
P.S. I also forgot about the parts:
CPU – FX 8350 (125W)
GPU – Sapphire R9 390 Nitro
MBO – Gigabyte 990 FX-UD3
Cooler – Hyper 212 Evo
PSU – Corsair CX 750
RAM – I think I have 16GHz somewhere
1. Look for any PSU rated above 850W branded as Seasonic.
2. My FX-8350/Asrock Extreme6 is set to 4.7 GHz with just a basic 212 EVO and push-pull fans. A decent quality 240mm AIO should suffice. I previously used a 120mm AIO, but it didn’t perform as well as the 212 EVO.
3. Roomy case with strong airflow has been sufficient so far. However, with your dual R9-390 furnaces, additional fans might be necessary. What case do you have?
Found the RAM - two x Corsair 8 GB DDR3 1600 MHz modules
The case is Zalman Z9 plus, currently has four fans, one exhaust and three intakes (two front and one on the bottom for the GPU, plus space on the side and top for four more fans, since I don’t want a vacuum setup).

Located the ram - 2x corsair 8 gb ddr3 1600 mhz
My case is Zalman Z9 plus, currently has 4 fans on it, one exhaust and three intakes (two front and one at the bottom for the GPU, plus room on the sides and top for four more fans, since I don’t want to create a vacuum or too many vents in a tight space, which tends to disrupt airflow).
That’s sufficient for now. Like you, I think too many fans can cause airflow issues and extra noise.
However, with two front intakes you might be able to remove them (bottom*) and switch to top for exhaust. I’ve noticed that moving the exhaust to the top makes the biggest difference in airflow placement for mid tower models like this. But... if you upgrade to a 240mm AIO, you’ll need that area for the radiator.
*the bottom front fan likely isn’t delivering much air because the drive cage is blocking its path.*
I created a hole at the bottom, making my case feel like standing on "chair legs." This allows the PSU fan to get enough air and makes dusting or vacuuming easier.
I can't place the exhaust on top because of the space needed for the radiator. Maybe I could put the radiator on the side panel, which is already full of holes, or adjust it if possible. If the side panel works, I can easily rework it. Then I can move the back exhaust to the top. What do you think?
Also, would four fans cool the motherboard voltage regulators enough (I forgot what those are on the board)? As long as both GPUs run at full speed, what if I added some powerful intake and exhaust vents? I’m really worried about overheating and might even consider installing an air conditioner there. XD
The bottom line is, you won't know until you get there. The VRMs have a good heat sink on them (I had that UD3 board twice. Version 1 and version 3, I believe) If there is enough air flow thru the case, they will cool themselves. The dual cards are the only problem. They block air flow somewhat and create lots of heat when maxed out. Your air flow will naturally take that heat upward across the VRMs. The best thing to do is get the system running with both cards and the CPU OC, then see what temps are. We might be trying to cool the wrong component. Btw, I'd not remove the rear exhaust fan.
Here's another consideration... If you put the 240mm radiator on top, there are two schools of thought on its airflow.
(1) Its fans pulling in fresh air to cool the radiator, and its warmed air exhausted out the back of the case with the case fan.
(2) The other is use the rear fan as intake for fresh air and mix that with warmer case air to cool the radiator and exhaust it out the top of the case. See what the AIO manufacturer recommends. I kinda prefer the first scenario.
You may even want to scratch the AIO solution and stay with a high quality air cooler. Makes for easier air flow setup.
This is an excellent deal on a 850w Seasonic and this is a very good air cooler at a great price.

3 intake and 1 exhaust???? You need more exhaust fans ESPECIALLY if you're going to be running 390s xfire. You want to get that hot air out ASAP.
I would go front, bottom, and side intake, and top and rear exhaust. When it comes to overclocking a FX and running crossfire, you can't have enough fans.
Those cards are really tough in airflow situations. They’re just too large and even a slight change creates a lot of heat. I experimented with two exhausts, one back, and another above the first one, but didn’t achieve your desired results. I was drawing 5°C more heat from the core and socket area, which likely caused a vacuum near the CPU. During idle, my cores were running at 25 to 27 and the socket at 35. With this configuration, I get 30 on the socket and 19 to 20 during core idle. Prime blends push it up to around 50 on the socket and 41–43 on the core (hard to recall exactly). Small adjustments bring it to about 55 on the socket and 46 on the core (though I’m not sure). On a 4.2 GHz processor at stock voltage, the voltage drop is 0.013V when under prime, but it drops to 1.272V during full load for 24 hours of prime time. That’s pretty rough, and it’s definitely not ideal. I have some extra room, but I’m unsure how other components would handle it if I increased the frequency to 4.4 GHz on that PSU (I’m not very technical).
For CTurbo the third intake isn't doing much—it's meant to bring fresh air to the GPU because it's very close to the ground. The top of the case is perforated so air can escape, but I don't think about the fifth exhaust. Thanks for the links.
What are the options for Seasonic Platinum 1000, ss-1000xp, 1000 w or Thermaltake toughpower dps g 1050w? I'm still focused on 1000w power supply.
