Default H75 vs H90 tubing length.

Was just about to buy H75 to go with HG10 when I seen H90 this is a 140mm rad this will be better than 120 rad?

Is the tubing length on the H90 same as H75?

Thanks

140mm means also a bigger radiator, so the 140 has more heat dispersion as a 120mm. If you don't going to overclock your gpu, then you can cool it with a 140 a 120mm AIO. But if you go overclocking the gpu, then you better of with a H105-H100igtx. With a 2x120 or 2x140 AIO you can keep your fan speed low, so no noise, with a mild overclock, and if you go al the way, then you have enough reserve ( fan speed and 240 or 280 rad) for doing this.
Watercooling is keeping your temps down with almost no fan noise, that's why you see builds with 2 x 480 radiators in it. So I would say, if you can afford it and you have the place in your case, go for the H100i-H105-H100igtx or a H110iGt. I know that the hose of the H100igtx and H110igt are longer as the older versions. Here I have a H100i and a H80i, both have almost the same length of the hose, the h100i is a little longer, but not much. I would say that h90 will have a little longer hose then the H75, this because it's a 140mm AIO.

Sorry this isn't for CPU it's for GPU with HG10.

H75 will likely offer a better blend of performance and noise out of the box, but the H90 will do better - and quieter - if you add a second fan to it.

Tubing lengths are roughly the same.

Where did I wrote that it was for a cpu, cooling a gpu has the same demands as cooling a cpu, the rule is 1x120mm for each component, but these days it's almost 2 x 120 for each component. a H90 will cool it, but it will do it with high fan speed. That is why I said better go for a H100i or H105, these are little more expensive as a H90,but if you don't have the place then a H90i push/pull will do the job if you don't overclock the GPU Also generally if you going to watercool a gpu you already did that with the cpu also, most people will go custom when they also going to cool a gpu. But hey everybody do what they want.

This is inaccurate.

Graphics cards transfer heat much, much more efficiently than CPUs do. We've kept R9 290X cards downright frosty under just an H75 and didn't need to run it at full bore. We're planning on eventually bundling HG10s with H55 coolers and believe me when I tell you they work well.

You can get even better cooling by jumping up to a larger cooler like an H100 or above, but a good 120mm will most definitely do the job.

Thanks
Question do you know if the backplate from msi 290 gaming edition will still be OK to use? And if so am guessing I should use the screws from my gpu and not the screws from HG10.

Honestly not sure if you can still use that backplate. You can at least try, but I'd compare the GPU screws and threads to the HG10's screws and threads to make sure you won't damage the HG10 by using different screws.

Thanks again, yeah I'll double check them against the screws of the hg10. Am guessing the Msi cooler will have longer screws to compensate for the backplate.

I hope I can it will look much tidier :D

I know it's an old post, but I'll share my experience with using water cooling on GPU.
I tested 3 differents AIO on a Inno3D 1080TI x3. In its standard air version it has 3 fans makes no noise at idle, and a lot of noise at full load while temp goes up to 83°C !

With the same setup, I tried a Kraken X62 (2x140cm radiator), then a Corsair H80i v2 and finally an Arctic Liquid Freezer 120.

With all 3 I got the GPU below 60°C in a deadly silence (made sure fans will not blow to their maximum speed as there was no need to save a few °C).

Both Corsair H80i v2 and Arctic Liquid Freezer 120 have larger than usual radiators (4.9cm against 2.5 for most) so it might help.

Those 60°C are achieved with a EVGA FTW3 1080TI Hybrid in SLI with the Inno3D. Actually with both 120cm models I achieved even better results because I was able to pull more fresh air in the case with the saved space!

Last note, I tested without SLI and only the Inno3D in the case (with the Arctic CLC), now the GPU temp is down to 45°C max in again a deadly silence! I believe it's because less heat is generated and I can extract more air with a 140cm fan at the back of the case.

I've also put the Arctic radiator to push/pull air into the case instead of the opposite, which appears to help a few degrees. All depends on the air flow configuration of the case obviously.


Long story short, I don't believe you'll need a 240 or 280cm radiator for a GPU, better save some space to create good airflow!
