Im going to do this as soon as I get my hands on some glue (please recommend which type to get) and Dremel disc for cutting plastic (tomorrow or the day after tomorrow)
Please feel free to stop me if you see any problem :)
Here´s my plan: (TL,DR version at the bottom you monster!)

I recently bought an HP Omen (GTX 960m version) for around 1500 euros (refurbished). With that money I could have gotten a much better specs laptop, but I love the laptop design so decided to buy it anyway.

The thing is beautiful and works nicely. However, the noise when idle and the heat when playing games are starting to bother me quite a bit.

At max of course a gaming laptop is going to be loud, though during idle, the laptop still makes a low but audible hum noise thats kinda distracting. And the heat while playing GTA 5 is around 78 - 88C for CPU and 75-80 for GPU, which is ok, if there´s no throttling. But there is, and I´m too lazy to check if it´s CPU or GPU or both.

After much research and having used the laptop for a few weeks myself, I discovered the culprit of the high heat. The design of the laptop´s bottom is flawed, and I plan to change it a bit.

First lets take a look at the plastic bottom

As you can see, the plastic bottom blocks intake flow of the fans. Air can only get through the triangle holes and then the circle holes (see picture below). The holes are not even aligned, which makes it even harder to get good airflow.
The double layer holes create bigger turbulence, which makes the laptop at idle noisier than it should be.

Look at the flashed area, you will notice the 2 layers, triangle on top and circles under it.

I plan to use Dremel circular saw disc to cut the triangle layer out, the cut area is red lined in picture 2. Then cover the area with dust filter material, most likely my gf´s old stockings :).

I believe this will help the air flow, lower the volume of the fan AND filter dust out of the laptop. I can change/clean the stocking once in a while easily.

Problem I might encounter is the triangle and circle layers are attached to each other permanently, in which case I will only cut the squares where the fans are, exposing only the fan vents.

What do you think of the plan? Will you encourage it? And do you think the Dremel will do the job of cutting the plastic? Any other suggestions?
Also, to remove the bottom, I have to remove the rubber strips. Reapplying them will need some glue, which type of glue ( gluing rubber to plastic) would you recommend me? I don´t want something too strong that I wont be able to remove it again the next time I want to open up my laptop, but not too light that it wont hold after a long period of time.

TL,DR version: new laptop is too loud when Idle and hot + throttles when playing demanding games. I will cut the bottom plastic cover where the fans are to remedy the problems. Check the pictures and texts above them for clarifications of the plan.

Thanks for reading!

Looks like a pretty sound plan to me mate. That is a truly shocking design though, no wonder it runs hot! Could you not drill the holes through the triangles, so at least they'd line up and get a bit of airflow? Obviously wouldn't be as good as your original plan, but I'm lazy, and that would be far easier :D
 
I've got one of these too, and although I really only play Elite: Dangerous (horizons) it's not too noisy at all , I have v sync switched on and if it's off it gets noisy, I've not really played anything other than tomb raider and Kerbal space program so not really stretched the machine .
Great little laptop that looks uber cool. And is pretty powerful for its size

Thanks for the suggestion mate. Not that bad, but considering Ill have to buy new tools and glue, might as well do it the proper way anyway :)

Have to admit the laptop is gorgeous.Though sometimes I regretted not buying a better bang-for-buck laptop because of the noise and the heat. My ears are sensitive so even the idle hum as it is right now is unacceptable, also I would like to limit the amount of dust going into the laptop as much as possible, hence the mod. Ill visit hardware store today to get some needed tools. Will update it and let you know if you need to do the same with yours when the time comes ;)

probably isn't there needs to be a balance of airflow inside the case to cool the rest of the chips on the board not just the cpu and gpu
ie power charging circuit

I went ahead and did the mod. I'll upload the pictures and results after a few days, not at home and not with the laptop right now.

Initial tests shows quite good results. I'm particular happy with the idle noise. Now when putting the laptop on flat surface, I hardly hear anything. As for the heat, was running GTA 5 same settings as before, temps were around 73-78 C for CPU, GPU never reached 73 C (before they were 78-88 C and 75 -80 C GPU). Admittedly the tests were done in around 30 minutes so probably the laptop were not fully heated up yet. Also I haven't done any stressing or benchmarks.

I'm still experiencing throttling here and there, and it seems like the GPU, I couldn't tell why would it throttle, very frustrating. So you might be correct that some other chips on the board are overheating.
 
While you'#re in there routing around, check the contact between the heatsinks and the chips - I' always like to replace the TIM with some AS MX4 while I'm cleaning out all the old dust - you'd be surprised how much difference replacing the gunk can make and how poor contact can be when they fit these at the factory!

I've not done it on a HP, but I have on a Clevo, several Dells and thinkpads...

That was the plan, though they stripped one tiny Philips P1 3mm head screw, I couldn't remove the heatsink to replace the thermal paste. Any tips removing a stripped tiny head screw?

Just drill the head off it, shouldn't be too much hassle as long as you're careful not to let the drill slip :)

Do mean you've rounded the part where the screwdriver fits in?
If so you may need to use a needle file to cut a slot in the top, or possibly needle nose pliers to get a grip on it.
Can you rotate the back plate to loosen the screw (with the other 3 screws removed :) )?

Yes the part where the screwdriver fits in was stripped, but not by me, it was already stripped when I opened the laptop. I assume it's been stripped when they maintained it, this is a refurbished laptop after all, quite annoying since the screw is tiny (3mm P1 philips) and looked like it's been tightened really hard.

But I'll leave the problem for a later day, since the laptop seemed to be dissipating heat quite well and fast.

Some tools:

First, removing the rubber strips

Done!

Prying time!

Time to grab this bad boy

Turns out, the triangle layer were NOT PLASTIC! I broke one saw disc, it hit my face, luckily my skin is thicker than ceramic (Sorry, no pics). Time to change the speed settings.

After cutting, not the best looking cut, but whatever :D

Finished! :D :D :D

I just figured out it was MSI Afterburner throttling the GPU when GPU temp is 72C. Uninstalled that ****, got NVIDIA Inspector instead.
Now the laptop does not throttle any more. GPU temp when stressing for 2 hours is 66-70, and CPU is 70 - 87. CPU sometimes peaks to 90 for a second.
At idle, the laptop is noticeably more quiet than before the mod. I can now just clean the dust filters and put them back, protecting the inside of the laptop.
I'm quite satisfied with this mod.
