If you're wondering why two sets of memory are listed, the Kingston HyperX Predator used in our other Haswell build reviews would not fit with the added thickness of the TD02. As shown above, the radiator overhangs the edge of the motherboard, and although the Temjin TJ04-E case fan opening is offset to give more clearance, there is only enough room for a standard height DIMM. As many performance rated or overclocked memory utilizes taller than normal heat spreaders, this may also create an issue with other memory and/or cases. You'll also note that due to the length of the TD02, the rear exhaust fan had to be removed and the optical drive relocated to the second 5¼" bay to leave enough room for the SATA connectors, even using those with 90° angles.
The TD02 was installed with fans above the radiator, drawing air through the top of the case and pushing down through the fins, as suggested in the installation manual. With mounting brackets on both sides of the radiator, there are other options we might have considered. For example, we could have attached the radiator directly to the case and hung only one fan under it, leaving enough room for the taller memory. But for the purposes of this review we'll stick to the recommended installation and switch to the standard height Crucial DIMMs.
You will need access to the bottom of the motherboard during installation, as the mounting requires a bolt-through arrangement. A universal backing plate for Intel and AMD is provided and threaded pins slide up through the holes in the board where spring-loaded screws can then be tightened down over the slotted arms of the block. The installation method is fairly typical and certainly no more difficult than any other similar bolt-through design.
Since the majority of users who would purchase the TD02 will likely be overclocking, we won't bore you with stock temperature results. Let's pick up where we left off with our previous air-cooled solution and jump right to 4.3GHz at 1.2V to compare. As you can see from the graph above, the Tundra TD02 drops load temperatures 11°C and idle temps by nearly 15°C over the Thermaltake cooler. Granted the Frio Advanced was certainly not one of the best air-cooled heatsinks we've tested, however this does demonstrate the clear advantage AIO liquid has over heatpipe air coolers. This happened to be the max ceiling for stable operation we were able to achieve previously, let's see if now with the TD02 we can push a bit further.
It took less than half a tenth of a volt more, 1.24V total, to hit the next 100MHz milestone, 4.4GHz on our Haswell chip. This increased load temperatures by 5°C yet still remained under that 80°C threshold. Unfortunately it appears that's where our 4770K happens to top out. Booting to 4.5GHz was no problem but any serious load continually resulted in failure, stepping up voltage one hundredth at a time. It appeared for several minutes we finally had a winner at 1.34V, however temperatures eventually climbed above 90°C and the process terminated. Going to 1.35V or above only caused temperatures to climb more rapidly, and our test to fail sooner.
Compared to other 4770K overclocking results such as those presented by [H]ardOCP it appears we have only an "average" or possibly a slightly "below average" chip. Judging by their Luck of the Draw findings, the majority of 4770K processors top out at 4.5GHz while only 30% or less are capable of going higher. And our temperatures are seemingly right in line as well. With up to 1.30V, a dual-120mm AIO such as the Tundra TD02 is suggested while for voltages greater than that, a custom water cooling loop is recommended.
Let's wrap up with some final thoughts and conclusion.
