H100 didn't seat properly

A few weeks ago I built a new rig which included a H100. Soon after the install I was hearing this grinding sound, I contacted OcUK and they started an RMA, the sound did actually stop the day after so I just left it.

About a week ago it started again so today I called up and will continue the RMA and get a replacement as this particular sound is common with the Hydro series coolers.

I was running a moderate 4.2GHz overclock on my 3770k with load temps reaching 68c and Idle temps of 36c which I didn't feel was that bad. After removing the H100 to return it I noticed there was a patch in the center of the H100 thermal paste which wasn't actually in contact with the CPU.

I've installed the stock Intel cooler for now until my replacement arrives but I'm really quite concerned about this patch of thermal paste which is still intact as my idle temps are exactly the same now as they were with the H100.

Here is a pic of the CPU block and the paste. Ignore the finger print, I had just done that :P

As far as I could tell the CPU block was fixed securely so I'm not sure how this happened.

Thanks
 
Which motherboard? Some boards require the pump block to be rotated by 90 degrees to avoid clashing with caps around the socket, failure to do so results in poor contact with the chip.
 
I have the Gigabyte Z77X-UD5H Intel Z77, there is plenty of room around the socket so wouldn't have thought that was the problem.

I am right in thinking that it's odd that part of the thermal paste has no evidence of CPU contact right?
 
Can't see your pic as they are trying to unthaw

More Hydro problems than you can reach with a barge pole. And ram problems.. and PSUs that they say has an "Ultra Quiet fan" you can hear from across the room... And then expect customer to pay post to return a defective product!!! I just figure if I buy a new product and it has a problem, I should get a replacement free... with no out of pocket expense...

The manufacturer sold duff product and as such should shoulder all the cost of replacement. Full stop!!

As things now stand I will never buy another Corsair product.. NOT EVER!!
A mate had H80 making noise right out of box.. Had to pay through the nose to post RMA to Holland or wherever they are... and replacement wouldn't even run!!!... and had to pay again!!


My Phanteks of 6 months use being off/on/off/on/off many many times and many many fan changes, I noticed one of the bottom fins felt a little loose. Emailed Phanteks, give them my addy, receive a replacement 8 days after first contacting them, tell them return is packed and ready, and it will be picked up at my door tomorrow. Not a pence out of pocket...

Contacted Fractal Design after I lost some of the HDD screws asking where I could buy some... They sent me a hardware pack free...

Contacted Noctua needing mounts for U12P SE 1366 needing mounts for AMD and newer Intel. They send me complete mounting kit with a smile.

Had a Western Digital start acting up after 2 years. Had 4 of same batch. Contacted WD and they not only sent me placement for sick one, but sent replacements for all of them!! Asked me to put old ones in packing new ones came in and put the supplied return sticker on them.. They did ask for my credit info on hold in case I didn't return them all. ;)

Have replaced Compaq/HP monitors the same way. No fuss, no muss.

I could show more examples but I won't

::gets down off of soapbox::

anyways, will see if your frog is thawed out yet. :o

Many coolers have a very big footprint. They will usually clear 40mm RAM.
CPU to side cover determines how tall cooler can be and how big fan can be. If your RAM is 38mm and new cooler has 140mm fan you will need 178mm mobo to side cover for fan to fit. ;)

image is now opening.. yeah.. I had to mark it to see if it was but it is..

Now that is one very strange looking seating print.:confused: The wedge shaped bit doesn't look like it ever contacted CPU. :confused:

If I had to guess it would be it never fully seated. Heatsink rocked side to side enough to stick TIM to edges and pull loose but wedge never made contact.
 
Well there is plenty of room for the CPU block on the motherboard:




I guess ill have to cross my fingers that the new H100 doesn't have he same fault and that I can get it to seat properly.
 
It looks like when the heatsink was tightened down on CPU it did not pull down enough.

I hope you get a good replacement too.
 
Maybe the backplate wasnt pushed through the holes enough and when you went to the front of the case to screw it in the corners didnt fully tighten as the things from backplate wernt pushed in enough through the holes so the cpu cooler couldnt seat as tight as it should have? I know when i put the backplate on my antec 620 the screw things on the backplate had to have a good push in to go all the way in and even then when i tried screwing it from the front the top left one seemed to stop earlier than the others. Which i found the corner of the backplate popped back out slightly so i went and pushed it in and tightened it more as it was pushed in fully when i was pushing the thing in while tightening it.

Maybe something similar happened with your mounting it and hence it couldnt be tightened fully in all 4 corners. Did it seem that one or two corners finished tightening earlier than the others?
 
Tbh I didn't notice any thing that felt/looked odd :S New one should arrive early next week and if the pump isn't grinding ill take extra special care when mounting the backplate.
 
is the surface of the cpu IHS actually flat o_0?

btw, fix for 90% of reported h80/h100 problems:

tilt the case around
flick the tubes
oriented the rad so the air gets trapped in the rad and doesn't circulate to the pump (important for h80)
last resort firmly tap the pump unit itself.

Yeh I tried all that, what I was doing the past week was tapping the CPU block and the grinding would stop but would eventually start again, sometimes it was 2 minutes sometimes a few hours. I got sick to death of doing that so continued with the RMA :P


Ill have a look at the CPU when I mount the new H100, it did look flat, would be totally unexpected to see it actually uneven :O
 
This H100 product sounds a mess. From grinding pump sounds to failing circuit boards to leaks. Over on OCN someone's H100 leaked onto his GTX670. Took a while to get it resolved but Corsair were only initially going to refund him $150 worth of damages even though his graphics card cost a lot more than that. Corsair are changing their policy on these all in one coolers for leaks.
 
Installed the new H100 today and so far it's as quiet as a mouse. Overclocking it atm and reaching 74c @4.4Ghz with 1.26v.

I have Gelid GC-Extreme sitting here that I've bought and am pondering whether or not to use it.

Some people are saying the stock H100 paste is good, some say the opposite. Any thoughts?
 
Is the temps even (ish) on all cores when at load? Did you check the cpu spreader see if it was curved or not? Just wondering about that wedge on the previous h100 and seeing if it was that or somit else.

Yeah flicking the tubes usually resolves my H80 grinding noises, not too fussed as it's just in a spare machine. The H100 in another seems flawless too.

Another quick fix is unplugging the molex for the pump unit for a moment. When I first encountered (in my main rig) the issue I did some searching and it appeared fairly common so I didn't bother replacing it, infact I jumped into doing my 1st WC loop so in some respects I have the fault to thank for that!
