Need to shave off a few more C degress with water cooling upgrades, need opinions please :) - Page 2

post #11 of 61
I have a pretty similar setup. Running the pump at 24v should shave a couple degrees off of your temps. Apart from that, running push pull should help a bit.

Your GPU temps are not an accurate way to measure the delta, the GPU is making its own heat and only being cooled by the water.
Again unless you have a large ambient to water delta taking a few degrees off your water temp with expensive upgrades won't get you that much change in CPU temps.

I see. well, that's a point. All I have at my disposal is the Infrared Contactless Thermometer (use it on MB heatsinks, e.g. for RAM or VRM areas when I get curious) and last time I hit the reservoir walls (acrylic) with it it showed me 28C while the GPU (downclocked at idle) at that time was at 31C if I remember correctly. ambient was around 25C I think ... still it's inconclusive, I know.

I was thinking about a different approach to estimate the water temp. I have an inline drain valve (brass inside) with a drain port. that "block" is nickel on the outside (not that it means anything specific haha!) and it doesn't sit on anything generating heat - would it help if I measured it's temperature to have a close estimate on the temperature of water flowing through it and let's say compared it to reading off the acrylic reservoir walls?

In (not close) future I will be getting a G1/4'' temp sensor with digital led display.

thanks for confirmation! rep+

Seems like I will be getting that 24V controller first and then more and more fans over time ... smile.gif


I think from lack of spare funds I might install my 2 spare XSPC Xinrulian 1600rpm fans on the push and see if it improves anything. I checked all over the internet and it seems there is only 1 seller left (Koolertek) still offering my Scythe S-flex 1900rpm fans ... hmmm, perhaps I should snatch a few of them before they run out of stock and discontinue like all other stores did ...

... or could I mix & match Scythe S-Flex 1900rpm @ 75CFM with Scythe GT AP15 (1850rpm @ 58CFM), what do you think people? AP15's amazingly are back in stock everywhere smile.gif

all right, I dug up my credit card and pulled the trigger on 24V pump controller and 5x AP-15 fans, will see how it goes for me. hopefully I will be able to achieve the goal with all of that at once and room AC at same time he he wink.gif

forgot about 1 more thing I may do to lower under load temps at 4.9GHz - disable the CPU Hyper Threading biggrin.gif

goodies coming in tomorrow if all goes well.

so far this is what I am getting when stress testing a fully stable 3770K @ 4.8GHz (no WHEA warnings) ... hitting 100C at around 25C of room ambient.

let's see if upgrading D5 pump power to 24V (for benching needs only, it will be 12V for daily needs still) and adding push fans (to current pull only) config truly improves things as supposed too biggrin.gif
if all fails then I will have to resort to AC at full blast and some cold air routing management around the case he he wink.gif

Replace all of your 120mm fans with some Delta 5200rpm/62dBA/240CFM fans. It'll fool people into thinking there's a jet engine in your room....I remember putting them on the laser cutter at the lab I intern at O_O.

haha LOL lachen.gif that would surely make the difference ... not only in computer temperatures, but even in my life in general ... This computer stands in the living room, I don't want my wife to abandon me wink.gif

That seems very high. thinking.gif

yeah it is. at 4.7GHz it hits 91C, at 4.6GHz it hits 82C. there seem to be the jump in voltages and heat generation past 4.6GHz...

it's my second 3770K and runs even hotter than the former one.
I also swapped boards recently, because my former one had some alignment trouble around CPU socket (cooling block was making poor contact with IHS) and now that is good, but my chip is hot regardless ... I totally hate the TIM under IHS idea on 1155 Ivy Bridge ... intel screwed up on it.
It used to be only a CPU lottery regarding voltage requirements, now there is also another factor - how well the TIM under IHS was spread out in factory... I hope Intel makes the next CPU using the old good solder method.
