I just had a look at my back plate and yeah, I ****ed up.

The back plate is not on properly, which comes as a relief that my H80i is not faulty. The only problem is that now I'll have to reseat it and being Xmas eve I'll have to wait until new year to buy thermal paste (I'm going away to visit a mate for 3 days on the 27th)

I'll report back with my temps in the new year when i get it reseated.
Thanks everyone for your help

Default H80i / H100i high temps FIXED!

Hi all!

First post in this forum.

First of all, thank you for keeping this thread alive!! it solved my H80i problems, and saved me from returning my corsair product and most important of all, it kept me from waving goodbye to corsair as a costumer.

To sum it all up, i also had the unreasonably high core temps on my CPU after i installed my H80i as described in the corsair manual.

I solved my high core - low water temp problem by adding washers to the back plate on the H80i back plate! and it WORKED PERFECT!

Below you will see pictures of my entire build, and my OC running temps (4.5 GHz)


Original build with bad temps: (and high noise from the stock corsair fans):



After removing the H80i Pump and cooling plate i saw this:





So, the solution was to ad about 3-4mm of washers on the back plate of the CPU mount: (sorry for bad pics)



After adding the washers i also changed the two 120mm stock corsair fans because they are absolutely terrible! i switched them with two 120mm arctic cooling F12 PWM´s and even under load in 4.5 GHz mode i cannot hear them. They are perfect for the H80i!



Last but not least, some data from benchmarking: (only CPU stress test..)



So, at this point i use one output on my H80i to control both F12 PWM´s on the radiator, and the other H80i fan output to control two 120mm fans at the top of the case.. Perfect setup in my opinion.

I sincerely hope this will help some of you guys!

BTW i fixed my H80i firmware problem using this guide:

Interesting stuff blicher69

I finally got around to reseating my H80 pump,as I've been away and had to wait for my nearest PC shop to open after Xmas/new years.

Thought I'd share some pics I took this afternoon, then I saw that blicher had similar looking problems with the pre-applied paste.

IMG_1019.JPG

As you can see I had **** all contact with the CPU.

I've replaced the paste with Arctic Silver 5 as it was all they had (despite their website saying otherwise) and followed their instructions precisely. I'm already noticing better temps, but I will give it the full 200 hours (or more likely 2 weeks) before I give my final judgement.

Thanks again for the help guys.

Don't worry about the 200 hour burn in time too much. Your temps might be 1-2C cooler later on, but testing for that in a normal room is difficult. If your temperatures are reasonable now, you did it right.

Cool

My temps are certainly better than they were, but in a few weeks I'll probably check anyway to see how good the contact is. I'm kind of curious to see how well I did it and to see if I should use more/less paste.

BTW got idle temps down from 42-44C to 33-36C so that's gotta be good (haven't checked heavy load yet), but as I noticed when I removed the pump my contact was pretty rubbish.

So the question is, is this a function of poor paste application on the original water block or is it a lack of compression of the water block to the CPU? The washers that are outlined above would lead me to believe that it is the latter, as pulling the water block closer to the CPU will not only reduce the amount of paste necessary to "fill the gap" but it will also minimize the thermal barrier between the cooling block and the CPU itself.

Was this how you had the notches on the backplate aligned before?

This was the first thing I noticed as the notches do not align with the 2 screws on the CPU socket. What is even worse is that you can clearly see how badly that motherboard is now bending around the CPU socket from the overnighting that you may be able to slide a dime under the CPU socket back plate (silver) (not the hydro black plate)

Below shows the correct way to install the back plate.

This picture helped me a good bit when installing my back-plate yesterday.

On a side note, I noticed that when I screwed in the stand-offs into the back-plate threaded holes that the back plate had a good amount of slop (probably ~.060" if I had to guess, I work in this scale all day long, so Im usually pretty good at estimating) but when I attached the cooler to the CPU, it seemed to tighten up just fine and I got pretty good thermal compound spread (unlike some of the other pictures that I have seen in here).

Is this normal?

Thanks Dustin! I did some further reading and it sounded normal. I installed my H80i and i am getting GREAT temps at 4.4ghz 1.25v on a 4670k (like 60-65C using AIDA64)

Really not much more I can ask for :)

I found a decent setup for my LED fans also, so I will just keep the stock fans on the H80i

At ambient of 75F, I get 28C idle, 54C gaming, and 62C full load from P95, AIDA and ETU.
Couldn't be happier with these temps at stock speeds for the 4790k. The H80i does a great job on performance mode, keeping temps in check, but not full throttling.

excellent forum glad I found it. Some good reading and excellent tips. I added 4 small washers I bought form ACE hardware, just to "snug -up" my pump a bit. dropped my temps 5C. Arctic cooling MX2 paste...

4770K 4.3Ghz @ 1.220V

Ambient 36º Celsius
Idle: 39C Max on cores
Gaming/Partial Load: 67C Max
Prime95 V26 Blend: 85C Max

Edit: had to edit, needed 1.2vcore for 3hours prime run, now its stable pretty much.

Hello everyone,

really nice thread here! im not very sure if my H80i is running okay im a bit worried that i might have an issue like blicher69 regarding the pre-applied thermal paste. i want to check but im not an expert i had this PC built for me so im worried about screwing things up. also i currently don't have any thermal paste, before going out to buy some and actually "try" to check on my H80i i would like your guys opinion,

an overclocked i5 4690k to 4.2Ghz at 1.130v
Idle temps are: 25-31c
gaming temps are mid 50s to be honest it depends on the game some mid 40's but games like GTA V pushes my temps upto 63c
Rendering clips can get up to 65-68c
stress testing on P95 Small FFTs take my temps upto 77c after 25 minutes or so..
Intel burn test takes it to 87c!! :o

Do these temps seem fine to you or should i consider re-seating and reapplying thermal paste?
my H80i config is set to push-pull as exhaust and i have 2 120mm fans as intake installed infront of the case
case is Corsair Spec-01

thanks guys! :)

Sorry for bumping the thread.

Default Re seat!

You should definitely re seat.

Do it with washers on the backplate if needed. Your temp is way to high.

Be careful with the washers ;)
