Overclocking study – Intel Core i7 4790K & Intel Pentium G3258 – air, water, phase-change, DICE & LN2
Goooood morning LAB501 !!! Finally, the article you have all been waiting for is here ! Heck, to be honest, this is also the article we were also waiting for. Even since the dawn of LAB501, we always wanted to do a complete overclocking study, using most of the cooling methods out there. And we never did a full study, because we are very thorough in our work, and each time we would start we would give too much attention to one of the cooling methods and in the end we could not treat all cooling methods properly. Just imagine that one of Ramiro’s air cooling reviews had 96 pages, and you will understand what I am talking about.
But enough about that – now we finally managed to do a full overclocking study, starting from air cooling and going through the most important stages. It doesn’t matter what type of overclocker you are – you might be a casual overclocker who wants to boost his system’s performance in daily-use, or a hard core LN2 user who didn’t try Core i7 4790K or Pentium G3258 yet – this study is for both of you!. From normal ambient air-cooling to low ambient air-cooling, from All-In-One water cooling solutions to extreme water cooling, from Single Stage phase change cooling to Dry Ice, and finally all the way to Liquid Nitrogen… we have tested all!
It’s all about numbers in this study, and that is why we didn’t test one CPU, but two – the overclocker’s dream Intel Core i7 4790K, and the budget overclocker Pentium G3258, or Pentium 20th anniversary edition, as it is also known. If you want to have the most powerful gaming rig, or break world records – Intel Core i7 4790K seems the logical choice. If you want to have fun overclocking, or maybe learn how to do it, Pentium G3258 is a great first step, and it is also very affordable (72 USD).
But we didn’t just tested 2 CPU’s… this review is also a team work result between my colleague matose and me. He is the one who spent hundreds of hours in the lab pushing the CPU’s with all the cooling methods available, and he is going to show you the results and analyze the scaling, while I am going to explain each cooling method we used and which users it is suitable for.
So… are you excited? Are you ready for a great journey from air cooling to liquid nitrogen? Are you ready to see some impressive numbers? Then join us as we guide you trough one of the greatest overclocking adventures ever. Let’s go!!!
