Dangerously high stock temps (4770k + h80i)

Hi everyone,
I'm having a very unsettling issue with my new build. My 4770k temps are very high. I've reapplied thermal past twice/re-seated the cooler. I even RMA'd the h80i because I figured the pump was shot and not working correctly. I replaced it with a 2nd new h80i with unchanged temperatures. I'm really not sure what else to try =(

Components:
Motherboard: Gigabyte GA-Z87MX-D3H
CPU: i7-4770k
Cooler: Corsair h80i

Temps:
Idle: 45-55C
Small fft (prime 95): 100C+
Blend (prime 95): 85C+ after 5 minutes.

I'm extremely frustrated because I KNOW my temps should not be this high, even if I was dealt a bad hand in the CPU department. The case has plenty of airflow with Noctua radiator fans (I tried the fans that came with the h80i as well, no luck).

Any help would be greatly appreciated.
Steve

YIKES! It has be your vcore, make sure it is below 1.3v.

And make sure use multiple temp monitors to make sure one isn't lying.

You many need to re-seat the cooler block on the cpu and remove the old thermal paste. If I'm not mistaken the H80I had leaking problems when they first came out. If that is one of the models there maybe no coolant in it. MY idle temps for a 4770K are about 30c at idle. Your temps are very high and would look and make sure the cooler block is seated properly.

Try To Apply the Thermal Paste again;

1. By Cleaning Both the CPU and Cooler's Baseplate Surface completely by use of any Surgical/Alcohol Spirit.

2. Then Apply Thermal Paste (A good quality Paste/Grease is advised) in the Middle Of the CPU with a Line Shape http://cdn.overclock.net/d/d9/500x1000px-LL-d9384fa3_DS...

Hey guys, thanks a lot for the responses. So this is actually the 3rd time I've applied the thermal paste/reseated the CPU when I installed the new h80i today. Because of this, I'm really doubting it's that. I've used a rice grain sized amount so I know i'm not applying too much.

Get this though, I have the radiator outside of the case right now just to make sure it's not an airflow issue, and I've removed both of the fans on it. I'm getting the SAME temps with no fans pushing through the radiator as I am when they're connected. So, this radiator isn't cooling my system AT ALL. What blows my mind, is this is the 2nd h80i I've tried, so I doubt the pump is bad.

I've checked all the connections and am giving it sufficient power via sata. The fans controls are working great through corsair link. I'm really at a loss here.

@TechyInAZ: My voltages are normal. I'm around .75v idle, 1.174v under load. This is weirddd.

Hello,

To rule out the cooler: check if both pipes are equally warm. If they are hot, then the problem is the radiator itself (clogged or something). If only one tube is hot and the other is cold/slightly warm, then the pump is malfunctioning or there is something wrong with the cooling agent inside the cooler (something blocking the flow).

@Cristi72 Thanks for the reply, neither pipe is hot, they feel room temperature to me. The radiator doesn't seem to warm up at all. What are the odd's that I would receive TWO busted h80i's? Just seems to unlikely but I guess it's possible. Is there anything I could have done wrong during the install? It seemed fairly straight forward but I'm a little out of options at this point.

sigh.

The pump is connected and working? You must hear a slight humm coming from CPU area. If not, then indeed the pump is broken.

Thanks again for your input. I'm listening for the humm but it's tough for me to tell what is the pump and what is my GPU and case fans. I'm pretty disappointed in Corsair at this point.. in the Link software it's telling me the pump is pumping, very frustrating.

Best solution

So I figured it out, and the solution is beyond annoying. There should have been some documentation for this within the Corsair installation manual and the included necessary hardware.

The back plate on the motherboard had about a 2mm gap, so the standoffs on the front of the motherboard, although tightened down, were sitting about 2mm higher than they should have. The block was mounted and 'barely' touching the thermal paste (it felt secure and on tight). I have an mATX case without access to the motherboard from the back, so I spent this evening disassembling the entire computer to put in 8 washers on the back of the motherboard back plate. Mounting these washers on the front of the motherboard will do nothing. Here are a couple pics to show you what the problem was:

Before the washers were installed on the back of the motherboard:


After the washers were installed on the back of the motherboard:


It's a shame that I had to return a product, then troubleshoot to this extent, but i'm glad I figured out the problem. I won't be purchasing another Corsair heatsink anytime soon.

My temps now:
Idle: 28-32C
Small fft (prime 95): 70-74C
Blend (prime 95): 50-54C

Thanks for everyone's help, I hope this post will help someone else with this issue.

Wow, that is indeed unexpected...

Please ask an ADMIN to make a sticky for this or make a new thread in which you can explain the steps you have made for troubleshooting the problem; the forums are full with complaints regarding high temperatures when using Corsair systems...

try 26.6, the newer versions of prime95 uses avx which makes intel chips way to hot. my h100i gets up to 80 degrees celcius at stock on 4790k but when i use 26.6 it is around 62

You were absolutely right. Just gave it a go:

Small fft: 55-58C
Blend: 50-55C

I think the root of the issue was still the back plate, but this is great. I'm very happy with my current temps. Thanks :)
