Most of my small projects usually have moderate success but I thought I'd post this up as it turned out to be surprisingly effective and could give others ideas for alternate methods of quiet cooling, who don't mind their case looking like a medical waste bin.
Long story short as possible... 980ti EVGA Superclocked etc
1. ACX 2.0 was pretty much rubbish at 4k, 80c+ constantly
2. Installed Accelero IV, knocked about 10c off. Got greedy for better temps...
3. Installed EVGA Hybrid combined with the rear heatsink from the Accelero, also a single 120mm blowing on the VRMs etc (No blower as it's not a reference card) Very effective cooling wise...
Pump noise horrible. Did some testing, when the pump is run at 7v it maintains basically the same temps as 12v with a lot less noise. Getting about 22c idle and max 57c under load. Pump then died on Hybrid (2nd hand so no RMA) on reflection the 7v may have knacked it, can only speculate.
4. Installed my original planned abomination (Pictured below)
The front and back heatsinks from the Accelero... Combined with 3x 120mm Nanoxia Deep Silence fans, mounted on an Alpenfhn PCI bracket directly under the heatsink. All 3 are wired directly to and controlled by the card, they never go over 30% (As per my fan curve) Case is a Phantom 630, so it has a 200mm side intake blowing air directly under the fans.
The results were unexpected for air and something that's pretty much silent and never ramps up etc.
Idle: 25c
Under load: 48c (Witcher 3 for an hour)
Under load: 51c (MGS V for an hour @ 4k, pretty much highest settings)
That 51c is the highest I've achieved. Worth noting the OC was hitting around 1500 / 8000.
Granted, it's ugly as sin (Yep, that's fishing line) with the finesse of a sledgehammer but my case only has a half window (No window if it was up to me) so you can't see it. Happy with the trade off and the much welcomed silence though.
