i7 920 temp query

Prime temps no higher than 50 doesn't say very much, it's important to specify what processor (preferably what heat load, but we can't have everything) it's dealing with while at 50. I take it that's what's written in the email, not what they said over the phone?

I like that ocuk test things, Id rather have something returned with "it works fine for us" written on it than have something new turn up doa which then confuses the hell out of me during further diagnostics.
 
Yep automated email response. Then the next email was to confirm shipping back to me.

I have left a message with them asking for test rig specification and also the testers opinion on the sloshing from the rad, we will see what the outcome is...

Also didn't like the way they seem to think I'm a complete amateur with thermal compound.

Just to make it clear, I'm not trying to put anyone off of OcUK as I think they are a good company!

I wonder if I could return it under DSR and get a new one?:confused:
 
*sigh* not happy..

just not happy.....

nearly £30 out of pocket now to be told its fine, not only that the item was returned with half of the original Corsair packaging missing! WTF

last time I RMA anything to OcUK - I should have RMA'd direct to Corsair
 
OcUK are alright, but occasionally you'll run into a monkey. The website has a complaint function which directs your comments to a manager who is likely to take you more seriously. Include previous rma number, preferably the name of the guy who lost some of your packaging and failed to notice it working incorrectly.

Don't just leave it at this, I firmly believe in reporting crap employees. OcUK as a company are very good, but one fool who should be fired can turn hundreds of customers away. If no one complains, his superiors will take longer to notice. They'll resolve this for you if you bring it to the attention of one of the more senior techs.

Good luck
 
That is really bad news mate.

What was said about the sloshing sound from the rad?

It definitely shouldn't be making that kinda noise, that's for sure.

Probably would have been a better idea to just RMA directly with Corsair themselves.
 
cheers guys,
I have left two messages with them expressing my concern, mainly the shipping charge and the fact that I went out of my way to pack the box with plenty of protection..

just cant get the staff these days eh lol

I have reinstalled the unit, and @stock prime95 temps are sitting at 63, max 64 so 1/2degrees better than before
 
Just wanted to say good luck, hopefully OCUK will come through. I'm no expert but sloshing certainly implies air within a closed loop system, probably manufacturing fault at time of sealing the system.

Its definately faulty! i've got CM690 case too and on air cooling with titan fenrir cpu cooler max temps are 49-50 degrees C on 2hours of Prime95 stress testing (3.6ghz at stock voltages).

Mate, think you did the right thing by trying to go through retailer first, think most people would do the same. Just a shame about "dodgy" employee.

Good luck.
 
If you can just post a screen shot showing the pump and fan speeds (maybe use speedfan?) there is a lot of relevant info in such an image.

also try turning the fans around (if u havent already) so they are blowing in the opposite direction than they are now.

a photo of your set up is also important.

my h50 is blowing out the back of my cm690, where is yours blowing to/from?
 
cheers guys,
I have tried with two different fans on the rad, 1000rpm as opposed to 800 and its made 1degree difference, the air is blowing out the back in push pull config.

I can take a pic when I get out of bed lol

The pump itself is plugged into the PSU header and I have tried it in a chassis header - and made sure they are not throttled. The fans on the rad go into my Scythe controller and are on full blast.

I now have an RMA from Corsair themselves, however instead of it being "tested" they will more than likely just replace the unit no questions asked.

If anyone has a H50 that is not installed could they give the rad a gentle shake and see if it sloshes please.. Thank you
 
sounds like you are using some poor performance fans. especially a fan that spins at 800rpm? what fans are you using? why dont u use the corsair supplied fan?

might be the case that you are also drawing hot air over the rad , depending on the airflow in your system and how many other case fans u got.

remember that its a sealed unit, but that does not mean its filled 100% with water, mine isnt filled 100% with water and it works fine.

honestly, you already rma'd to overclockers and they said its fine, why waste your time and money sending it to corsair before you hahve ruled out all the possible problems with how u got it set up?
 
I haven't read everything in this thread so apologies if it's mentioned already:

I found with my i7 920 that I got the same temps at stock clocks as I did at 4ghz. As I understand it, idle temps and temps without an OC are less important when using water.

Am I wrong?

originally I was using a pair of scythe gentle tycoon fans in a push pull config push pulling air from inside to outside the case. I have now swapped my two ceiling fans over for the scythe ones and see the same sort of results

also have a fan in the front of the case cooling the 4 hard drives, and a side fan also

bear in mind that the temps are the same with the case side off so plenty of cool air getting to them

to add to this, the head exchanger on the H50 is so warped its unreal. you can rock a rule across the "flat" - clearly it needs lapping

I am unsure what to do now tbh, do I spend more money sending this f..king thing to the Netherlands or not bother and either put up with it or go back to air cooling

scythe gentle typhoon @ 800rpm:

Air volume at full speed (12V), CFM ±10% 28.2

cfm of corsair supplied fan is approximately 50cfm.

lapping the copper suface wont invalidate ur warranty.

try using a better fan dude, those scythes @800rpm are clearly not up to the job.

im using the corsair supplied one and ill be using an apache to push when i can be bothered to open my case up again.
 
Airflow means jack all for a radiator, I'd be astonished if the gentle typhoons were worse than the supplied corsair. The 1450's are very popular for radiators, a single 800rpm gentle typhoon would have been my choice of fan for this cooler.

Further testing can't be bad though, supplied fan is the obvious one. If the air coming out the back of the radiator feels hot, it means the fan is inadequate. If it's cool and the chip is roasting, it means the contact or heat transfer from plate to fins is inadequate.

What you need to do is get through to one of the managers at ocuk. Call up and insist on elevating, if you're unwilling to do this then there's not really anything we can do for you.
 
I will be on the phone on monday dont you worry!

I have just tried 3 different fan setups.

1. 2 Scythe gentle tycoons in push pull setup, temps circa 68degrees
2. 2 Artic Cooling AF 12025 in push pull setup, temps circa 69degrees
3. Corsair recommended pull setup with their supplied fan, temps circa 71degrees

:confused:

Sounds like I'm starting to get one peoples nerves, but ultimately I hope this thread helps other people that might be experiencing the same characteristics.

For what it is worth your results are worse by several degrees than my stock i7 and air cooling with Noctua NH-U12P SE2 in an ATCS 840 case.
 
I don't suppose you have used an air cooler on this chip before you got the H50?

Or do you have an air cooler that you could use?

I'm curious to see if you have high temps with a different cooler.

A photo of your set-up would'nt hurt. Maybe, some of the eagle eyed guru's here can spot what's causing your temp that high.:rolleyes:

I agree davy, id prefer to work with a good proven air cooler such as a TRUE, its a more proven setup compared to the h50, a TRUE cant leak coolant fluid, its basically a chunk of metal, the h50 is a sealed unit, which unfortunately, like a proper custom watercooled setup you can replace fluid in the loop and add other parts, i think personally the h50 is a passing phase, in a short time well hear reports of the units failing.
 
I have tried a stock 775 cooler LOL it was a but toasty but good enough to surf the net ect. I also have a 775 Scythe Mugen - its a BEAST

I might give it a try and pop a pick of my case up today
