H80i v2 or H100i v2

Hello everyone!
Recently I've bought the CPU Corsair Hydro Series H80i V2 High Performance Cooler and this question came into my mind while i was searching for a new case.Now,as far as I know,the only major difference between the two coolers is that H100i V2 has a bigger radiatior(276mm),whereas the one on the H80i V2 has just 154 mm.I have an i7 4790k that i intend to overclock up to max.4.7 and i was wondering if I'll have some "problems" with H80i V2.Does the H100i v2 cool better because its radiator has a bigger length?I don't think i'm gonna change my H80i v2,but I really want to know if I had got a better performance with the latter one.

Bigger radiator better cooling, especially if you plan on overclocking. Many here will tell you to ditch the Corsair and get a better radiator/pump combo. Preferably something made of copper.

A general rule of thumb I like to go by is have one 120mm radiator dedicated for each component to be cooled and a 240mm radiator if you plan on overclocking that component. And finally a 360mm radiator for two overclocked components.Naturally as radiators get bigger the more trouble they are to fit inside a case.

In your situation I would go with the larger radiator.

That's a good question. Earlier Corsair models had some problems but lately they have been much better. Is it still possible? Absolutely. I've had an H100i V2 in my system for 2 years and it's been working fine. Keeps my overclocked CPU in check. My radiator is mounted in the top of the case, so to answer your question, yes it can be mounted up there as an exhaust setup.

If you're asking me, I have an I7-6700k currently overclocked to 4.5 GHz. I see core temps in the high 50's to low 60's with an ambient room temperature about 20-21 degrees C.

I've had the h80i V2 for about a year for my 6700k. If you just want it for "silent" cooling, it's fine. But for OC, I'd go with a 240mm option. I have the OG Antec 300 and it just doesn't have room for a 240mm rad so I went with the 120mm. It just doesn't have the surface area to compete. Now, my 6700k isn't great but to maintain stable 4.5 I need 1.34 on the voltage and temps are in the mid 80s. So, I run at 4.4/1.28.

As far as reliability, I haven't had any issues at all. Getting the software tailored to your needs can be a process but once it's set up you can ignore it being there.

Well, yeah, getting something made from higher quality parts with better heat dissipation capabilities and significantly better performance/noise would kind of be the logical thing to do......

Firstly,thank you all for your help,I'll definitely know better in the future.However,I cannot see myself changing the cooler in the forthcoming future,still,when I'll probably change my CPU and MOBO i will reconsider buying a new cooler as well.Nevertheless,as I'm still going to overclock my CPU,even a little,this question poped up in my mind.Where is the best place to fit the 120 mm radiator? Is it at the rear or the front of the case,or it simply doesn't matter?
Thank you again!

4.7 isnt really asking a whole lot with that chip and cooler. I never had a problem hitting that on any of the 4790k rigs ive set up. I do have one friend hitting 4.8-4.9 with that cooler and a 4790k but he has put some effort into the fan placement and flow through the case as he also runs SLI 970s. A larer radiator would of been a better solution for him. Anyway, That cooler should be able to get the job done at 4.7 unless your chip isnt a good clocker and requires a lot of voltage for the clock speed your after. Mounting on the top is fine if the airflow is there for you..

Fill your rig info out and put it in your sig so we can see what all your running.

Well,i was thinking i could put the radiator at the front,in that i think at the back it would simply look too cramped.I sure want to arrange everything so that i have a good cable management,air flow,and a neat and tidy case.Furthermore,as far as i know,the cooler has already a termal paste applied,so i shouldn't worry about any paste,right? Also,should i clean the CPU with something to remove the older paste from the old stock cooler before i set up the new cooler? Is there any chance to destroy my CPU when overclocking or it has a safety procedure when it automatically shuts down in order to prevent any damage if temps are high?I am going to monitor them,but still,i want to know everything before starting "playing" with my rig.

If you mount it at the front as an intake keep track of your gpu temps because you are dumping hot air into the case.

Definitely clean the chip with some isopropyl alcohol and mount the cooler. The cooler will/should have paste applied. There is always a risk when overclocking but the chip will throttle before it damages itself.

Here is a nice Intel temperature guide if you have time.

If the H-80i is new then yes it has thermal paste on it out of the box and its good enough material to use. you will definitely need to clean the old material off of the CPU. I use a lens cleaning towelette but any towelette with a little alcohol on it will do the job. Overclocking always carries a risk. But Since you are aiming for a very moderate OC ,your not going to have anything to worry about. For 4.7 I would just increase the multiplier and call it a day. No need to mess with the other settings. The CPU and mainboard have thermal and overvoltage protection that will be adequate for a 4.7 OC. You really shouldnt run into any issues. Heck on my wifes rig in my sig, her 4790k OC's to 4.6 just setting the XMP settings for the memory. I guess what im saying is that if 4.7 is your goal, no sweat. If you start getting greedy, then time to back up and read up on overclocking on that mainboard.

Ok,so it seems I'm good to go.I have recently read a lot of guides about overclocking as I intend to do it as a hobby and moreover to learn something new(i always seek for new information).I read somewhere about someone who started overclocking and couldn't get bored,so he was always looking forward to improving.I think that's what I'm going to do,especially when I'll be on my own salary,and not parent dependent,so yeah...
Anyway,thank you all for your answers and wish you all the best!If I'll have any further question I know where to find you
