No Heat coming from fan/rad?

george_tbt3 · 26 Oct 2013 at 23:38

Hi there,

I currently have new rig
H80i cooler
i7 4770k
ASUS Maximus VI Hero
8GB RAM
NZXT PHANTOM 3.0 case ( h80i fans conected to mobo not Y splitter)

My problem is at 4.2 ghz cpu level up my temps are instantly hitting 80 degrees ( also happens when fans connected to y splitter) there is no hot air belting out the radiator, after 5 mins of stress testing i feel the grid on the rad warm and the tubes a little warm, should the hot air not be blasting out the back? seems very strange, when i disable prime the temp shoots back down to 30 lol? used corsair link newest version, doesnt show graph or power tabs? i have the USB plugged in and the sensor. i tried with stock cooler, at default bios 2 mins of prime before it bsods on me lol, 100 degrees but all i feel is the metal fins hot but not warm air blasting out could be due to the TINY fan mind you >.< I have reset the coolers and also resat the i7 chip! help me please.

p.s the system BSODs at 4.4ghz kind of stable with 3.100v but 90 degrees >.<

3.1v?! Surely you mean 1.3v?

Also, with Haswell chips, under the lid they aren't soldered, so they rise in temperatures without dispersing much heat onto the CPU heatsink, so that could be why you are seeing massive temperatures and the rad not warming up much.

You mentioned a tiny fan.
What do you have there?
H80i stock fans should be fine.

He was talking about the stock cooler.

i tried with stock cooler , at default bios 2 mins of prime before it bsods on me lol, 100 degrees but all i feel is the metal fins hot but not warm air blasting out could be due to the TINY fan mind you

Are your fans on that H80 positioned in right direction ? :-)

I know, silly idea but I have seen that in another rig once :-)

The radiator should feel rather hot when the cpu is over 80 degrees. Not quite burn-your-fingers hot, but definitely noticeable. The tubes should feel warm too.

Either you've installed it incorrectly or the pump is faulty.

Have you made sure you removed the plastic film of the bottom of the cpu block ?

First of all what program are you using to stress it? Prime/Intel Burn Test are no good on Haswell and the recommended programs to give it real world stress are Aida64 and Passmark Burn in tests.

And as far as the rad/cooler is concerned it sounds like the same fault as I had. My cpu temps just got hot when doing anything and got silly hot under load. I noticed that the rad was cool but the pipes 2-3 inches from the waterblock/pump head were hot. On removing the cooler upon turning the rad upside down a couple of times you could hear that there was very little coolant in the unit. I rma'd it and the replacement was fine.

Haswell doesn't generate a lot of heat to be honest, the chip itself only gets hot due to the poor heat transfer to the heat spreader.

george_tbt3 · 27 Oct 2013 at 14:07

there is little warmth on the radiator but this is after around 4 mins of prime 95 testing, there is cool air coming out the back of the case, I have made sure the fans are the correct way around, it was the same with the stock cooler although with the stock cooler the metal heat sink gets hot but due to its stock fan it doesn't throw of much heat due to its size? the h80i I feel the block connected to cpu warm and the tubes eventually warm up butits a gradual thing not instant like with my previous h50 and i7 930, that would throw of heat instantly! I take this is how haswell works compared to sandy bridge, could it be I just got a poor chip? to the other post I mean 1.3v cant hit 4.4ghz. I have made sure there is no plastic cover on the bottom of the cpu blocks, also reseated both cpu blocks, there was nothing melted to the cpu lol so that is not an issue. I just thought haswell would give of as much heat to the rad as an i7 930 would, doesn't seem right?

Jokester · 27 Oct 2013 at 14:51

i7 930 would be a 50-100% or so more heat than Haswell, especially if you were overclocking.

To be honest the heat from the rad will never feel "Really warm" like a GPU exhaust heat does..

Run Aida64 for 30min so the coolant temp warms up, if it's still blowing cool air, then something is wrong.

george_tbt3 · 28 Oct 2013 at 00:18

well my previous h50 blasted out heat, a few people have said this is how haswell works? is this not bad for the motherboard if the chip is hitting 80 degrees, once it hits this point i hear the h80i fans hitting max speed on prime but its just cool air throwing out so it is installed correctly? ocuk has not got back to me on this matter

george_tbt3 · 28 Oct 2013 at 03:14

I have been reading online that the backplate of the h80i is loose on the maximus vi hero some people add a washer or two, it gives better temps and tightens the CPU to the block. Due to the motherboard being pretty thin. Any feedback on this is much appreciated please.
