So, I am new to overclocking and just wanted to know a good speed for the i5 6600k, but when paired with the Maelstrom 120k AIO liquid cooler. I already have both obtained and was just unsure on how much this cooler could handle. Thoughts on both topics please?

A 120mm rad for overclocking... Um, I highly recommend getting a different cooler. These small AiO coolers don't compete at all with good quality air coolers. It's when you get to the 240mm+ length radiators that water starts to show how useful it can be.

Do you have a way to get your money back on the cooler?

That being said, you can overclock on this cooler, but I imagine it will really hold you back. Technically, you can go up to 95C before anything can go terribly wrong, but I don't like to see these chips go above 85C. As soon as you raise your voltage at all (which you'll probably need to once you get past 4.5GHz), I'm sure your fan is going to scream and your CPU will still heat up somewhat. That being said, it shouldn't get dangerously hot until you approach 4.7GHz or so.

First off, I was thinking more around 4GHz. Second, I wont be doing this yet as I am still acquiring the Mobo, and Video card for this new build. The Motherboard would either be a GA-Z170-HD3 or Asus ZZ170-E. I know the asus is better, but it is what has me better for price. Power supply is the Corsair CX600. Video Card will be RX480 4GB by Sapphire. I do not intend to overclock anything else besides the CPU.
 


Do not overclock on CX power supply. You'll just cause problems for yourself.

As for the motherboard, the Asus one is actually worse. I'm not sure, but they decided not to put a heatsink on the MSOFETs above the socket but they did put a heatsink on the ones to the left of the socket. The Gigabyte model gives you six series of MOSFETs, all of which are properly cooled. I'd go with the Gigabyte model.

With a good power supply, your current cooler will get you to 4GHz without issue. After all, 4000MHz (4GHz) is only 100MHz faster than the advertised boost speed. I doubt you'll even need to change voltage to reach this speed.

Why can I not use this power supply? And even if I did, what kinds of issues would I run into.
The pieces I have are as follows ( I am using some from current build)
i5 6600k
Corsair CX 600
Deepcool Maelstrom 120k
2 WD HDD ( 1 TB and 500GB)

All I need Now is a Mobo, Video Card, And Ram. I only really want to overclock to 4GHz, so is it even really worth it? I can grab a Gigabyte G1 B7 Sniper For $85 CAD. I would rather get a Motherboard like that if it isn't really worth overclocking to 4GHz. Also, the video card is the Sapphire RX 480 and Ram will be ant that fits the colour scheme. Should I just rely on Turbo? BTW That Sniper Board is $40 CHeaper than the nearest Z170.
 


B150 does not allow CPU overclocking. Only Z170 does that. That's why there's such a large price difference.

As for the power supply, your current unit is known to deliver unstable voltages once you place a high load on it. Something like overclocking will definitely do this. Even if you don't increase voltage, raising the core clock increases the amperage the CPU pulls through the motherboard VRMs which get their power from the PSU. If you can't afford a new PSU right now, I'd just rely on the built in Turbo speed.

If we look at the Tom's Hardware PSU Tier List, we see that the Corsair CX series is in Tier 4. Tier 4 is described as "Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice." Tier 4 is the worst of the worst from reputable companies. Tier 5 is all units from non-reputable companies.

You may have misunderstood what I meant by the last post. I know you can only overclock on a Z170. I was asking your opinion on the product that I showed you, because now I am not going to overclock. Now, there is the Sniper G1 B7 for $85 CAD, or should I purchase the Gigabyte GA-Z170-SLI For $99? Even though I am not overclocking would this Z170 board be better for future?
 


The sniper is a great board. It will serve you well.

If you're not planning on overclocking, why pay the extra money for an unlocked CPU? The i5 6500 may be a better fit for your system if you're not going to overclock.

It was given to me as a Christmas Present, and it was the same price as the 6500 at the sale time.
