    I am a member at alienowners.com and have been directed here to discuss concerns with the cicichen multi-pipe heatsinks. After much research, I found that cicichen's heat sinks offer better cooling performance, and help to control GPU and CPU temps to something more reasonable (I would be happy with 75c under load).

    I am running an Alienware 17 R1 (Ranger), with a GPU upgrade to a 780M and a CPU upgrade to a 4900MQ, stock was an 860m and a 4510mq(?)

    I ordered the four pipe heat sink for the GPU, and the 5 pipe heat sink for the CPU. The GPU one did drop my 780m load temperatures from 98c to 85c, no complaints there. But the CPU temps are not any better than before, and the 4900mq is still reaching 92-93c under load with the fans ramping up.

    Note that I also installed the 11CFM R4 fans, also purchased from cicichen.

    The concerns with the CPU cooler performance are pretty obvious when it comes to heat sink inspection. The die contact surface is wavy, and what looks to be a couple "pits". I don't see how this can effectively transfer heat away from the die to the fins.

    I contacted cicichen, but it seems like he is very adamant that the heatsink is perfectly fine, and just to use silicon grease to install it, challenging me that the temperatures are normal. Is this true? From what I have heard and read, his heat sinks perform much better than the stock ones (in this case the CPU heat sink performs the same, regardless of copper and increased pipe designs, and I fail to see how such an imperfect contact surface can be passed off as acceptable.

    They offer better thermal capacity and have better handling of sudden heatspikes.

    That being said the fan has to be ramped as well, with a max fan speed I was seeing 54-56c on my 780m and also the 1070.

    CPU is more difficult to cool though, I had to modify the entire chassis with a bigger fan and double the radiator to handle 4.4Ghz on the 4930mx with liquid metal. Though it made 4.2Ghz daily quite cool as the voltage requirements were much less.

    I apologize, I hit post before I was finished writing. I am working on getting pictures of the die contact area.

    I did install a PWM bypass switch, to ramp the fans up to max RPM, and it does help, but I feel like I got cheated on the heat sink with it's horrible contact area.

    Running your finger over the copper plate, you can clearly feel how uneven the surface is.

    I got both GPU and CPU heatsinks from the same guy and some people say it helped them, from my personal experience these are garbage quality. They are sitting in the storage, I tried to fit both of them and they didn't even screw down, damn thing was not even upto the HS measurements also same BS of uneven surface, when I tried to reach him out, same type of reply that it is fine and did I check my machine and etc. At that time I was like at-least someone is helping to make this AW 17R1 work efficiently and didn't give him a bad rep but I did mention it here too. It's been quite sometime (2 years) maybe that guy improved them as I see some positive reports but not willing to try again.

    Then we have this same PWM bypass, if we do not use that technique the high density Copper block that comes with that is utter useless as the heat will be retained in that and spread to other parts of the chassis. Personally I do not want to hard mod this machine for other reasons and here running a 980M fine with the stock HS (Phobya thermal pads, GC Extreme) and HWInfo fan control with M17x R3 CPU fan and M17x R4 GPU fan, both are better than Ranger's low CFM garbage stock fans by Dell cost cutting. I think stock HS is really a good one and if we can manage to add a few pipes like the German modder that's the best solution IMHO, and the extra lapping of Copper Shim for the 1070 upgrade since the new Pascal die on 1070 HP Black PCB chipset (natural upgrade path for 17R1 for Pascal without any hard mods) is thinner than Maxwell GPUs.

    I wish there is one positive note on the DPTF Tables working with Unlocked sBIOS, so far none for AW 17R1 (here on AW18), dunno why... and unfortunately that crap needs the drivers + an MX chip to make it work.

    I forgot to mention, a 980M with 3 Pipe Stock HS works perfectly fine (unless that 980M is blackscreening due to the missing mosfets) but you need to use a cooling pad (here are the mods using Notepal U3 thread 1, thread 2, post 1, post 2) and HWInfo manual maxout control, so for the 780M it should be even much better.

    Yeah the CPU heatsink from him seems to be hit and miss, the GPU heatsinks I've had were all great but it is anecdotal.

    I ended up making my own heatsink but its not something other users would be interested in.

    can you post your pwm modification

    The heatsink looks completely unusable from the pictures you posted. The most important part on the heatsink looks bent and dented, where is has to be absolutely flat. The whole point of the heatsink is to be flat as the metal to metal heat transfer is way better than the best thermal paste can offer (399wmk for copper vs 72wmk for thermal grizzly conductornaut). If the heatsink is bent, the thermal paste will have to fill in the gaps with the inferior thermal conductivity. There is no way that heatsink is fit for purpose at all. The suggestion to use thermal paste to fill in the gaps makes no sense.

    I don't think for the cpu side of cooling won't make any difference. I have a 4940MX in it right now , and after starting a game, you can actually cook an egg on contact on the side of the laptop where the HS and Fan reside.

    Improvements can only be done on the GPU side.

    PS: I even have a custom laptop cooler with (3) 120MM and (1) 80MM fans , still didn't help lol

    You have to create your own heatsink to get better temperatures, but thats more than most are willing to put up with.
