Noise was getting unendurable in the winter cold, so I took off the wretched 80mm trash Gigabyte stock cooler from the videocard, then took the single 120mm orange fan from my elderly Big Water 745:
It has the old-style power MOLEX cable soldered onto it, plus a single wire (onto motherboard pluggable) detector for something.. I took the Voltage=RPM regulator as well:
Here we have the slot covers for the hoses exiting and returning, along with the fan speed adjustment for the single radiator fan. I would have liked to have seen the dual radiator fans with a speed control.
The Big Water single radiator fan has - thank God - still the intact wires soldered onto it, so I could plug into it the above regulator, which now sits nicely on the backside of my bought used-on-sale HP 6300 Pro, which of course NO LONGER HAS ANY MOLEX connector on the PSU.
So I took the power cable + built in adaptor of my also old Conceptronic CSATAi23U USB SATA IDE: the adaptor on the right side and the 220V power cable.
This plugged in interestingly automatically begins to supply power, I don't even have to press the ON button on that oval assembly you can see built onto the cable to the right.
So now I had MOLEX power! Of course I needed a male<->female Molex converter, which the Conceptronic HAS on the left on above image. Unfortunately the power cabling attached to the Big Water Single 120mm fan MOLEX somehow got ripped off. So I cut the Conceptronic Molex power cable - ripped off half an inch of insulation from the four wires and after some experimentation with the naked wires
turns out that
for full fan power
the Yellow and Black colored Molex cables ought to be connected to the Big Water Single 120mm fan. So I stripped the cables of their cover and
folded the now naked cable's four wires together by
hand - the two thick wires from the Molex Yellow / Black connector paired to the two thin naked wires from Big Water Single 120mm fan power line.
Then as insulation I used a quality, super-strong (net-reinforced) duct tape for both Yellow and Black lines.
To "mount" Big Water Single 120mm fan into the PC case
- of course I did NOT want it to touch the GPU heatsink to MINIMIZE VIBRATION NOISE -
I put an aluminum slot cover into the PC case, right next to the nice stylish Big Water slot voltage regulator on above pic.
I glued a
special 2-sided strong duct tape (IRL used to mount smoke detectors onto bathroom ceramic tiles) on the backside of this empty aluminum slot cover. Onto the other side of the duct tape - now we are inside the PC case - I glued
a cheap and small two sided SPONGE with the hard green side. Alu Slot cover + sponge glued together.
The yellow soft sponge other side is looking toward the CPU cooler now INSIDE the PC case. But this yellow soft sponge side is too wide/thick, therefore is way too soft to hold any weight, it could NOT bear the WEIGHT of the Big Water Single 120mm fan.
So I trimmed this soft yellow sponge part into half and onto it I again press-glued
the special 2-sided strong duct tape and finally after some measurements I press-glued the
Big Water Single 120mm fan onto this. So now the alu slot cover is glued to the sponge is glued to the 120mm fan hanging - leaning low touching the bottom aluminum assembly of the PC Case and not really covering the GPU heatsink properly anymore...
I closed the PC Case with pulling all the thick and plastic black net-covered Big Water power cabling out of the case ABOVE the screw-less foldable HP all-slots LID COVER.
So when I folded this into place - with a nice click - it neatly jammed the Big Water + Conceptrix power cables firmly between the top of the slots assembly and the screw-less foldable HP all-slot LID COVER.
Now the heavy
Big Water Single 120mm fan is glued onto the soft yellow sponge glued to the alu slot -
to nullify any vibration sound - and on its top is being now
firmly held by the power cabling - running OUT of the case - but the cables are jammed firmly under the foldable slot cover
. This now prevents the 120mm fan from touching ANY METAL inside the PC Case, NULLYFING VIBRATIONAL NOISE.
Of course because of accidental lucky misplacement now the big 120mm fan is
NOT parallel to the PCI slots, but is irregularly turned by a couple degrees (6°?) and is now leaning over MORE over the Gigabyte GPUs naked aluminum heatsink
. So the GPU heatsink and the 120mm fan are NOT parallel in this jury-rigged setup. The fan is now leaning toward the slots and is turned more
toward the alu GPU heatsink leaning over it.
This misalignment resulted in a
-2°C BONUS temperature reading. By default the Gigabyte 80mm noisy cooler, - perfectly mounted ON & lining up nicely PARALLEL to the GPU heatsink - usually gave me 32°C idle GPU temperature. I have now with this lucky misplacement a 30°C GPU idle temp in GPU-Z. Under load the
-2°C BONUS temperature HOLDS,
VERSUS
to an earlier test-placement of this same Big Water 120mm fan when I placed it so it was nicely lining up parallel to the GPU heat sink.. Which gave WORSE temperatures!
Turns out, - thanks to the
TechPowerUp Review RPM DATA - , that I have this Big Water 120mm fan with the BIG Water voltage regulator running at its
1300-ish RPM = turned down to the MiNiMuM, lowest setting. It is wonderfully almost noiseless!!
Turning the Big Water Voltage regulator UP toward and at max setting it runs at a loud 2400
RPM, but I don't need it of course. Calm and SILENCE is paramount in my work. So it runs on most silent minimum setting.
The radiators are made simple and look rather well in black with chrome grill covers. The dual radiator fans generate up 54.4 cfm at 1300 RPM and the single radiator with the adjustable fan speed generates 38.6 ~ 93.7 cfm at 1300 ~ 2400 RPM.
All this jury-rigged inside a small HP 6300 Pro
with its sensibly designed factory air-cooling running. CPU air cooler, then my super-lame GPU 120mm fan jury-rig hanging from a soft sponge + held UP by the power cabling, plus the PSU fan
and
the hot air is sucked outside by a 80mm stock HP fan at the back.

Current GPU temp:
58-60°C playing Rogue Waters.
I tried to overclock the Gigabyte 730 GT to the maximum offered in an article on a big review site's forum:
1. Core Clock to +160
2. Memory Clock +450
and my machine froze in under an hour. Could have been a power problem as I have two old motor-powered thus heavily vibrating HDDs running + Gigabyte 730 GT + M-Audio 24/96 soundcard inside the machine with default CPU clock speeds, latter a little bit stronger than the HP stock CPU: Intel Core i5 3570 and all this
ON the original stock 300W HP PSU.
I just don't use the EVGA overclocker anymore.
My machine is finally running SILENT as an assassin. I slapped my forehead, how stupid I was not replacing this trashy Gigabyte 80mm GPU fan from the beginning and endured its horrible noise for years.
Now I enjoy a near silent Big Water 120mm orange fan running. I have sensitive ears..
PLUS: the GPU fan now is still running when I turn off the PC, maybe cooling the videocard a little bit more, until I flip the main power switch. It feels now this old used poor PC is running as per recommendations to leave the fan running after de-powering..
New fan is running since almost two weeks now. I'm at the mercy of the Conceptronic power-cable/adapter as it is old and can reach End-ofLife any time. But I used it rarely, so the power-converter inside perhaps will hold, until I'll buy finally a new PC with Noctuas.
BIG NOISE DIFFERENCE SOLUTION!!!!

Under the PC case I placed a soft folded bed cotton cover to minimize vibration coming from the 2 HDD motors:
I expect that SSDs + quality PC case + latest hardware will solve the old vibration problem in the future,.
