DeepCool CPU Cooler (LUCIFER V2)

Amazing cooler. Fits on i7 7700K and board ASUS strix Z270F Gaming. Cpu overclocked to 4.75GHz stable with this cooler and the temperature is no more than 78C under stress test. As a computer technician I have had the right tools to fit it BUT as others complained IT IS TRUE you NEED a special screwdriver to fit this. No any average screwdriver set will have a screwdriver for this.

(Note: when I bought this, it was £20, but it's currently only available for £50+. So while my purchase was definitely value for money, there's plenty of alternatives which are far cheaper than the current price!)The packaging for this heatsink is impressive enough to verge on the ludicrous; black box within a black box within a black box, like a nested Matryoshka doll. Though to be fair, there's a reason for this Apple-inspired plethora of packaging: the heatsink is huge, heavy and relatively fragile, so kudos to them for making sure it was securely packed!(And as other people have noted, it’s big enough that it’s best to check that it’ll fit in your case; I have a standard MIDI tower case, and I’d be surprised if there’s more than a pencil-width’s space between the “spikes” atop the heatsink and the case cover!)Installing it on my 1151 board (as per the generic 115x instructions) wasn't too bad. The simplest way to start is to put the securing pins in the bottom plate and then drop the motherboard onto it, after which you can add the risers and secure with the brackets.Attaching the heatsink to the brackets is slightly trickier, mainly because the heatsink has a significant overhang; you’ll need a long thin screwdriver to be able to reach the screws on the crossbar (or maybe long needlenose pliers to do it from the side). Something which isn’t immediately obvious is that the spring-loaded bolts on the crossbar are in a groove and can slide back and forth slightly; it’s worth double-checking that they’re positioned correctly before dropping the heatsink into place, as trying to manoeuvre them with a long screwdriver can be tricky!The final step is to attach the fan, using two thin wire “clips” - this is generally best done after securing the crossbar, as otherwise it’s even harder to reach the bolts. I’m not too keen on the clips - they’re pretty flimsy - but they seem to have done the job well enough and there’s two spares included, presumably in case you want to add a second fan to the setup.manouvreAfter that, the only potentially tricky thing is hooking the board back up to the power and data cables - the overhang from the heatsink is big enough that it could get in the way, though thankfully this wasn’t a major issue with my motherboard’s layout.Unfortunately, I didn’t take any temperature readings with the original stock heatsink, but with the new one fitted, my G4560 has been running at around 28C when idle, and only rose to around 40C when left to encode some 1080p video for ten minutes. And the new one is definitely quieter; the only significant noise is now coming from the PSU.So overall, I’m more than happy enough - though I do now have a large number of black cardboard boxes to dispose of!
