To celebrate Father’s Day, we strongly recommend you build a computer -- though that tends to be my recommendation for everything, including the celebration of a full moon on Friday the 13th (next one isn’t until 2049). This weekend's sales round-up features a 450W PSU for $40, 8GB of 2400MHz RAM for $75, a vapor chamber CPU cooler at $75, and a GTX 780 Ti for $600. Continue to watch our twitter and facebook feeds for more deals throughout the week, and subscribe to our YouTube channel for helpful tips.

Case, power, and cooling manufacturer NZXT announced new products in their liquid cooling (CLC) lineup today at Computex. The company debuted the Kraken X41 and Kraken X61 to members of the media at the Taipei-based computer electronics convention, alongside a new "GRID+" fan controller hub.

The closed-loop liquid coolers are follow-up products to the Kraken X40 and Kraken X60 that we reviewed last year. The X41 and X61 have kept the same 140mm / 280mm CLC design, but make additions in the form of variable pump speed control and increased radiator thickness. 

The weekend's sales round-up features 8GB of 2400MHz RAM for $76, a high-end liquid CPU cooler for $90, some LED case fans for $3, and a mid-tower case for only $70. Keep your eye on our twitter and facebook feeds for sales and news throughout the week.

Antec's 1250 CLC presently rules as king over our CPU cooling test bench. The liquid cooler uses a dual-pump design with fixed fans, ensuring rapid exchange of liquid through the radiator. Software controls the fan RPMs (silent, extreme, and custom speeds) in a manner that enables silence and extreme performance, depending on the use-case scenario.

All this stated, we're happy to announce that Antec has kindly provided us with a 1250 Kuhler for giveaway on the site.

This weekend's sales roundup features a low profile CPU cooler for $20, a Cherry MX Red keyboard at $107, 8GB of 2400MHz RAM for $80, and a high-end AMD AM3+ board for $200. Keep your eyes glued to our Twitter and Facebook feeds for more deals during the week.

Many of you may not be familiar with Cryorig. They're a relative newcomer to the PC Cooling game and have only just started putting out CPU coolers; last fall they released their R1 Ultimate cooler that reportedly did reasonably well for an initial release. Now, they're venturing into the small form factor arena with the upcoming C1 Cooler. Cryorig makes some bold statements when it comes to performance and seem to have done their homework.

With thanks to Antec, Cooler Master, and SilverStone, my boredom of closed-loop liquid coolers (CLCs) has subsided as more innovative designs have emerged. As we've discussed heavily before, a significant portion of the cooler industry goes through a single suppler: Asetek, who have a notoriously-long legal arm. Asetek's designs can be found most heavily used in NZXT and Corsair CLCs, and frankly, they're boring; they're rebadges with software options, in essence.

Antec's Kuhler H2O 1250 CLC blew away all other CLCs when we last tested a cooler, and now we're back to see if SilverStone can perform the same feat with their 240mm Tundra TD02 cooler. In this SilverStone Tundra TD02 benchmark and review, we'll look at the liquid cooler's installation, build quality, and thermal performance. This review will be a bit shorter than our previous CLC round-up and Antec 1250 review, as we've already covered many of the core cooling principles and can now focus purely on the unit.

After a suggestion from reddit user "Tangential_Diversion," we decided it'd be a good idea to do a sort-of collative post post-discussion from our reddit topics. For our regulars who might not frequent reddit's technology subsections, I frequently answer questions about new reviews, products, and PC hardware over here and here. Most recently, a thread about our Antec Kuhler 1250 dual-pump CLC review received nearly 100 comments, where I answered several questions about design and discussed the future of GN's test methodology.

This post will quickly round-up some of the Q&A from the community -- I'll also jump into some explanation of future plans for testing methodology toward the end.

Closed-loop liquid coolers first hit the market a few years ago, instantly becoming "the thing" to have; it was an easy solution for users who wanted to lay claim to liquid cooling, but didn't necessarily have funding / ability for an open loop system.

As these coolers emerged, it rapidly became evident that simply being a liquid cooler didn't make it inherently better than air. A solid, entry-level air cooler (like the AR01 or Hyper 212) will often out-endure and perform equally to a low-end liquid cooling solution. Just as with other aspects of hardware (a cheap Z87 board vs. an expensive H87 board, for instance), just because it's theoretically more advanced in one aspect, that doesn't mean the performance will outmatch a less technologically advanced product that employs higher-quality engineering. A tuned sleeper can blow past a high-end stock car, if we were to make analogous comparisons.

This weekend's hardware deals round-up is, from our perspective, a lot more exciting than the last few weeks; we found refurbished Corsair H100s for $50, a decent Corsair 430W PSU, a Dell UltraSharp 23" IPS monitor, AMD 7950, and FX-8320 CPU all on sale. And, because deal hunters also like free things, be sure to check out our FORCED game giveaway.
