redeyes posted:On Jays latest video he admits he won't use the pretty custom loops he makes for all his videos on his own workstation. Says it's too hard to work on and modify. LOL Apart from GPU waterblocks and the Skylake-X series I've never really been more than passingly tempted by custom loops. The gains just aren't worth the hassle and risk for 99% of users. AIOs are a decent gain (especially on GPUs) and actually are a plus for convenience in some ways (the block is much smaller than air coolers), so they are justifiable, but CLC is a huge commitment both right upfront and in the future since it's hard to take parts in and out. GPU waterblocks are the only way you get liquid cooling on the VRMs, which does really help efficiency and card life. All the AIOs (including the ones on the 295x2) have fans on the VRMs (although Fury X does run a copper pipe across the top which I guess is better than nothing). If I won the lottery I would love to build a really crazy compute rig with 7-8 cards on a board and that means single slot, and the only way you can do that is with custom waterblocks. Or, do a SLI setup in something like the Bitfenix Prodigy M, where cooling is just too much of an issue. And of course Skylake-X sure is a thing, although I'm not sure a custom loop is really any better than delidding in terms of hassle. Assuming they can fix the problems with leaking in the first-gen kits, EKWB does have a really nice setup where it's basically an AIO out of the box and you can buy "prefilled" GPU blocks that attach using quick disconnects. That seems pretty good to me. But unfortunately quick-disconnects not leaking is a fairly big ask. When I was growing up I remember the quick-disconnect air hoses in our garage leaking constantly, they are just an inferior connection to a proper semi-permanent fitting Paul MaudDib fucked around with this message at 20:31 on Jun 27, 2017 |

If you own a old second gen i5 with a 1070 and 144hz gsync monitor, is it wiser to get a ryzen 1700 or a 7700k? Strictly for gaming.

7700k but Intel's new stuff is coming soon and since you've waited so long already might as well wait a couple months.

I think he's referring to having front mounted with fans pulling external air in. While likely a small difference, it would be superior to a top-mounted radiator doing the same.

Are there any decent large-die-area low-power optimized processes (eg something similar to what you'd use for smartphone silicon that supports 150mm^2 dies or larger)? I wonder if you could do a low-power micro-Navi on that.

eames posted:I never understood why people mount their watercooling radiators to suck air into the case. It seems like the equivalent of having a 200W space heater blowing into the case. If you have a blower-style GPU cooler, having the radiator exhaust air makes the most sense. That way you can intake cold air for everything, and the CPU and GPU are thermally isolated. If you have an open-air cooler on the GPU, you need to decide what to prioritize. You can use the radiator for intake and let the GPU deal with the warmer air coming in, or you can have the radiator exhaust, in which case it has to deal with warm air coming off the GPU. It barely even matters, though, and probably only makes a couple degrees difference in worst-case scenarios. People just like to optimize their rigs.

sincx posted:Doesn't every 1 degree rise in temperature increase hard drive failure rates by a few percent a year? The first comment has already been responded to, but regarding the second: you have to remember that air is not good at conducting heat, because the molecules are too spread out to see a large amount of heat absorbed. Thus, as you'd expect, cold air is better than warm air at conducting heat, since the molecules are every so slightly closer together. So when you use a radiator to cool a liquid such as for a CLC, you're depending in part on the ambient air being cooler than the temperature of the fluid that is moving through the radiator and heating the fins, and also in that the fins are effectively reducing the opening area the air is passing through. The fan(s) pulling or pushing air in through a radiator are operating at some speed that corresponds to a flow rate though the effective open area of the radiator. Thus we're mechanically forcing the air to compress, which helps to increase, ever so slightly, the absorption capability of the air. In terms of internal case temperature, we're counting as much on simply engaging in air exchange of the internal volume, utilizing convection to reduce internal temperatures. The temperatures you then see inside the case are going to depend a lot upon how the system is set up (positive/negative pressure), the number of fans, whether filters are present, etc. Ultimately it's important to remember that it's easy to see internal air exchange depending on fan configuration and get the internal temperature down, but it's more difficult to cool a processor, and providing the greatest delta-T for the radiator's medium (air) is advantageous.

They are now selling "complete watercooling kits in a box" now with proper fittings and soft tubing runs you cut yourself. EK announced way back at the beginning of this year that they were going to replace the Predator AIO series with EK-MLC (modular liquid cooling) so that you could run an EK loop for your GPU only or something--I've read in a couple places that the transition to this new product line isn't going to happen for a while because 1.) EK moved a lot of their production work/storage space to a new place this spring and 2.) they're not really motivated to do it because Predator AIOs actually cut into sales of their custom loop parts/lines/kits

Yeah, those are the things I am talking about. I saw them when I went to go see if they had updated brackets and poo poo for AM4. As part of their featureset, they come with all-aluiminum radiators and waterblocks to zero the possibility of electrolytic corrosion as well. I haven't seen any videos on it yet, but I figure if anyone would have done a video on it by now, it'd be Jayz.

Hello friends, all my Ryzen stuff finally got here today. I did a quick overclock and I got my Ryzen 7 1700x @ 1.38V, 3.9ghz and temps are hovering 60-65 Celsius. I really want to try to get to 4.0 ghz, but looking for information I am seeing max safe temp ranged as anywhere from 75-95 and safe voltage as anywhere from 1.4 to 1.45. Anyone know what it actually is? Unfortunately memory is sitting at 2300mhz. When I tried to do the XMP profile 1, my computer went into a reboot loop and I had to cmos reset to fix it.

Whether or not you can reasonably get to 4ghz seems to be a bit of a lottery, although I assume a 1700x would have better odds.

I just put together a whole system sans GPU without really paying attention to the price turned out to be cheaper than the 7900X CPU alone.

Blocks not really, if you want to cool a second card right now the only way would be to buy a second kit. You CAN find pure aluminum radiators if you search around if you want to expand that way. EK has said they plan on expanding the line though in the future with more blocks/radiators/pumps/etc, but nothing beyond "later this year".

It pains me whenever I walk into my local computer store and they have EK loops with Thermaltake aluminium radtiaors that I just know are going to be completely destroyed by galvanic corrosion.
