    13900k + 4090 Loop capacity

    How important is noise? The Loop Configurator is a good ballpark estimate but that's all it is. Can't find numbers on the RTX 4090, but the worst RTX 3090 namebrand blocks generally had less than 20 C delta core to water temperature, so if you're fine letting your water temps rise you can run...

    Is water cooling still needed for good overclocks anymore?

    The air won't just be coming in through the obvious gaps, it will be coming in through any and all available gaps. This means corners and crevices that you didn't even know existed could be potential spots for dust accumulation. The unfiltered air would also likely mean eventual dust buildup on...

    Is water cooling still needed for good overclocks anymore?

    What do you have for your intake? Sure, you might get lower component temps, but generally peripheral temps suffer as a result. Additionally, with negative case pressure, dust tends to build up in all the nooks and crannies of the case. Positive case pressure ensures that dust pretty much only...

    Is water cooling still needed for good overclocks anymore?

    I disagree on this. I regularly let my coolant get 5-10 degrees over ambient, but it's far quieter than it would be with air coolers (essentially silent) and is still running at lower temps than it would be on air. Doing it per your specs means I would need a bigger case or put up with more noise.

    Plasma sparkplugs increase engine efficiency by 6% - 20%

    Yes, it had a 2.73:1 with a .7 overdrive giving it an overall gear ratio of ~1.9. The manual had a 3.45 with a .5 overdrive giving it an overall of ~1.7. Flip that around to the first gear, and the automatic had a 3.059 first gear for an overall of 8.35 while the manual had a 2.66 for overall of...

    Plasma sparkplugs increase engine efficiency by 6% - 20%

    With the C5 (and other GM vehicles using the T56 series of transmissions), the rear end gear ratio is higher to compensate for the high overdrive. The reason the C5 manual got better mileage than the C5 automatic was because of the 4 speed automatic's poor ratio spread, forcing a rear end ratio...

    Plasma sparkplugs increase engine efficiency by 6% - 20%

    From the article: At minimum a tune will be needed. I would totally be onboard with this if they're able to get tunes out for older cars.

    Is water cooling still needed for good overclocks anymore?

    Large AIOs can certainly compete with custom watercooling setups, but custom setups offer much more flexibility. Also large AIOs approach the cost of entry level watercooling, especially the good AIOs. I've always said this, from a price-performance standpoint, custom watercooling has never and...

    WC’ing blocks for MEM.

    Anything that puts things in series increases restriction. You will need a distribution method that puts things in parallel, but then flow balancing can be an issue. If one path has double the restriction of the other path, it'll get half the flow rate the other path does.

    Who is still using a Sandy Bridge era chip

    Went for it and just upgraded my 4930k to an E5-1680 V2. Using only quick stability tests, I'm able to run it at 4.4 ghz on stock volts, a 200 mhz improvement over the 4930k. 2 additional cores and an additional 200 mhz is pretty good for $70. The 4930k is going to replace a 3820 I have in...

    Aquacomputer Leakshield

    You probably are overthinking this. Also, not sure if you're reading things wrong, but the Leakshield most likely will not work, at least fully, if your combined head pressure is too high. The leak detector won't work if the leak occurs in a spot where the pressure in the loop is higher than...

    What went wrong with my loop?

    Welp, had to break down my loop (partially) due to a failed D5 pump. Didn't seize up or anything so I assume the electronics broke down. Manufactured in 2005 so it is a 17 year old pump. When I drained the reservoir, it was as clear as the distilled water I put in.

    Who is still using a Sandy Bridge era chip

    I have a 3820 and 4930k in two of my computers. There's a seller on Ebay with E5-1680V2s for $67 a pop, I might just have to pick up two of them to slap into my computers.

    Which Radiator Setup: 2 x 360 mm and 1 x 240 mm radiator OR 1 x 360 mm and 1 x 480mm radiator?

    You're already overkill as it is, so it's really up to you what you want to achieve. I would say at this point, choose whatever setup you feel like putting in the work for doing. If effort isn't a big deal, then choose whatever setup looks more aesthetically pleasing to you.

    Do people actually upgrade just the CPU and keep using existing motherboard?

    I remember during the AMD days going from a Phenom II days going from a Phenom II 965, to a 1055, then finally 1090. Jumped over to X58 and only ran it with an i7 920. X79 was my next platform upgrade, and that went from the 3820 to the 4930k I'm still rocking. Obviously I'm doing a full...
