Cooler Master Q300L v2 – Overpowered Micro-ATX Gaming PC Build

The Cooler Master Q300L v2 is a micro ATX case designed for building high-performance PCs with ease. In this article, we’ll delve into its features and components, which can be used to make a powerful build.

The Q300L v2 is a straightforward case that allows for creating an incredibly powerful PC without significant hassle. While it’s not categorized as a small PC, it is notably smaller than a typical tower, offering excellent component compatibility without compromises.

Parts

Let’s take a look at the parts we will need to build out this computer.

CPU: Intel i5-13600K

The central processing unit (CPU) chosen for this build is the Intel i5-13600K. This CPU has 14 cores, including 6 performance cores that can boost up to 5.1 GHz. A plus side to this CPU is that it can use both DDR4 and DDR5 RAM, which when paired with a DDR4 motherboard, can scale back expenses.

This being a high-end rig, another option for this build is the 7800X3D, which is largely considered the best gaming CPU currently on the market. (For more information on the 7800X3D, click here.)

Either way, the risk of bottlenecking even an RTX 4090 with this CPU is low, especially when gaming on higher resolutions like 1440p and 4k, where most people with a build like this would be playing.

As far as upgradability, it’s looking like the next generation of Intel chips will be using the same 1700 socket. This makes way for an upgrade path- at least up to the 14th generation. Although it is not certain, using a 7800X3D’s AM5 platform is supposed to be supported until at least 2025.

Motherboard: ASUS TUF B760M

The motherboard selected for this build is the ASUS TUF B760M, a mid-range option that offers essential features for a gaming rig, while still saving some money, as compared to a Z series board. This particular model has both DDR4 and DDR5 versions. Although the choice in RAM is up to personal preference, this build will using DDR5. This model includes 3 case fan headers, a front panel USB Type-C connector, PCIe 4.0 M.2 slots, a Thunderbolt USB 4 header, USB ports, Wi-Fi 6 capability, and USB-C on the back.

This model, however, won’t allow for overclocking. In my experience, I have consistently found satisfaction with the performance of the Intel i5-13600K at its stock settings, meaning that overclocking this CPU might not be necessary. However, the decision regarding overclocking ultimately rests with the user’s preferences and requirements.

Storage: Samsung 980 Pro m.2. Drive 

Moving on to storage considerations, simplicity often reigns supreme in my builds, and I typically opt for a single M.2 drive. In this instance, I’ve chosen the reliable Samsung 980 Pro. While a 1 or 2 TB capacity will suffice for most users, I’ve opted for a spacious 2 TB variant. However, it’s worth noting that the motherboard’s second M.2 slot remains available, providing an option for future expansion should the need arise.

Memory Configuration: Corsair Dominator DDR5 5600MHz

Memory plays a crucial role in system performance, and for this build, we’ve opted for 32GB of Corsair Dominator DDR5 5600MHz memory. These modules feature an Intel XMP profile, ensuring optimal performance and stability without compromising on speed.

Cooling: Scythe Fuma 3 and Noctua Fans 

When it comes to CPU cooling in the Cooler Master Q300L v2, users have several options to consider. While the case can accommodate a 240mm radiator at the front for those inclined towards water cooling, in this instance, we’re opting for an air-cooled setup. Our choice is the Scythe Fuma 3, known for its exceptional performance and quiet operation. Surprisingly, despite its budget-friendly price tag of $50, it rivals or even surpasses more expensive coolers in terms of efficiency and noise levels.

The Scythe Fuma 3 air cooler paired with Noctua fans provides efficient heat dissipation and quiet operation. This setup offers excellent airflow, crucial for high-performance systems. The Scythe Fuma 3 will be paired with a Noctua FH-1 fan hub.

Power Supply: Corsair RM1000x and RTX 4090

The Corsair RM1000x is a pretty large power supply, but still fits into this case very comfortably with no problems. This build will be using an RTX 4090, recommended to be paired with at least a850w power supply. 

Graphics Power: NVIDIA RTX 4090 Founders Edition

The GPU of choice for this build is the RTX 4090 Founders Edition, renowned for its compact size despite being one of the smallest 4090 cards available. However, due to their rarity, acquiring one can be quite challenging. Nevertheless, the Cooler Master Q300L v2 case offers ample space, accommodating GPUs up to 360mm in length, making it suitable for larger third-party cards as well.

Alternatively, users can opt for high-end AMD cards like the 7900 XT and XTX, which are excellent choices and seamlessly fit within this case’s dimensions. In fact, an upcoming build featuring the 7900 XT will soon be showcased, providing insights into its performance.

Despite its impressive capabilities, the RTX 4090 stands out for its unmatched performance, delivering exceptional frame rates in demanding games like Starfield. With frame rates ranging from 70 to 80 fps in 4K without using FSR and surpassing 130 fps in less demanding scenarios, it clearly outperforms other GPUs in its class. However, its premium price tag and overkill performance may not be necessary for the average user.

Step-by-Step Assembly Guide

  1. Gently lower the CPU into the socket, ensuring the gold triangle aligns correctly, and then close the latch for a secure fit.
  1. Remove the m.2. heatsink, insert the drive, lock it down and replace the heatsink.
  1. Grab the intel back plate from the box and align it through the 4 holes on the back.

  1. Slide on the plastic spacers with the rubber side pointing down.

  1. Install the  2 LGA 1700 mounting plates and secure them with the bolt nuts.

  1. Open the latch, make sure that the notch is correctly aligned, and then apply even pressure until you hear both sides click into place.

  1. Once the rear and front fans are installed, lower the motherboard into the case, align it with the standoffs, and then secure it.

  1. Feed the CPU power cable from the power supply and the fan splitter for the CPU cooler through the back of the case and connect. (The top is not removable, so it’s actually pretty difficult to make those connections even without the cooler installed, and nearly impossible if it was.

  1. Install the last top exhaust fan.

  1. Route the 24-pin motherboard cable in through the back and plug it in, along with the USB-C and USB 3 on the left-hand side.

  1. Plug in the front panel connector across the bottom, which is very conveniently combined into a single connection for user ease.

  1. Connect the HD Audio connector on the bottom right. 

  1. Plug the extension cable for the Noctua FH-1 fan hub at at the bottom and route it to the back.

  1. Align the removable power supply bracket with the power supply. This can be secured with the two removable screws.  

  1.  Grab the power supply and plug the other ends of those cables into the unit. (There should be plenty of room to lower the power supply with the bracket attached back into the case and re-secure it.)

  1. Use the space in the back for cable management. Plug the fan cables into the hub and tie down some of the cables at various points. (It doesn’t have to be perfect since the interior will not be seen.)

  1. Apply thermal paste to the CPU. Put a line down the center and spread over the CPU as evenly as possible. 

  1. lower the cooler into the case and align it with the 2 standoffs on the mounting brackets and tighten the screws switching off every few rotations to get even pressure across the CPU.

  1. Install the fan clips onto the 2 fans included with the cooler and clip the first one in the center by pulling the fan clip into the groove of the fins and then the same thing for the slim fan on the outside.

  1. Plug the fans into the splitter by connecting the slim fan to the white connector and the other to the black.

  1. Install now is the RTX 4090 Founders Edition GPU and lower it into the case. Slide it into the pCLE slot, and secure it.

  1. Plug in the 12-volt high power cable and make sure that it is pushed in completely.

  1. Re-install the side panels.

Now your build is complete!

The Cooler Master Q300L v2 is an excellent choice for building a compact yet powerful PC. Its features, compatibility with high-end components, and efficient cooling make it a compelling option for gamers and enthusiasts seeking a versatile and effective case for their builds.
