Hi Guys,

Some of you may have seen my new build and i have been experimenting with overclocking. I have overclocked in the past but that was with the C2D so a few year back.

So my setup is as follows;

Intel Core i5 3570K
Gigabyte Z77-UD5H
Avexir Core Blue 2666MHZ
EK-Supremacy Waterblock
EX-XRES 140
XSPC D5 Pump (set just under full speed)
Mayhems Pastel Coolant

So far with my clock at 4.6GHz (Voltage 1.30v) with the ram at 2666MHz (Voltage 1.62V) which seems to be running quite stable but at high temperatures.

What sort of temperatures should i be getting on this CPU at this speed?

CPU Ambient: 73'C
CPU Die 1: 81'C
CPU Die 2: 90'C
CPU Die 3: 90'C
CPU Die 4: 81'C
CPU Heatsink (Assuming that is a reading from the pump?):35'C
Mainboard Proximity: 34'C
GPU Die: 26'C

Please feedback :-)

These temps are using Prime95 and not normal operating temps
 
yeah 90 degs is a bit toasty, i would clean it off and remount you cpu cooler.

Is the CPU heating up the loop much? i found when i had bad contact my rad wasnt really kicking out any warm air cause the heat wasnt getting into the loop.

No not a double post, this is a thread asking in the correct location. My build thread noted i was having trouble.

No, not as much as i would have expected. I have tried twice remounting using Arctic MX-2 without any luck.

I am a bit reluctant to think its the loop, i can see the water moving quite a bit in the tank and i have ensured all air is out of the radiator.

I have contacted Amazon where i purchased the CPU and they are sending a replacement on the grounds that its running 75'C at standard frequency on water.

I will report back what the new CPU is like in comparison with the original one

I meant double post from me, i typed one msg then realised i couldnt undestand half of it and tried editing it and posted it again so i deleted and posted again. Too much stella.

Your proberbly just got a CPU with bad contact between the DIE and heatspreader, mine had terrible contact so i had to remove my heat spreader and go with liquid pro to sort it out, didnt help i had a poor clocker also though i need 1.39v to get 4.6 compared to your 1.3.

ohh right ^.^ my bad haha. least you had stella... i had night shift -.-

Im very very tempted to take off the heatsink if the new one isnt great. its a bit of a scary thought butchering a brand new cpu! im going to put the paste that came with the waterblock on when the new CPU is here tomorrow and if its not much better i will use the Liquid Ultra between the die and ihs and then between the ihs and the water block
 
Yeah its only worth taking the top off if ya having problems getting the temps down most people dont have problems with the heat spreaders effecting temps, im sure your next chip will be fine with the HS left on. If ya do end up taking the heat spreader off ya chip eventually, theres a few guides from people who have done it on the forum. When they first started putting the heat spreaders on AMD Chips years ago i used to cut them straight off, and ive taken this one off im using now, not damaged one yet and im not exactly delicate with my hands. :)

well i remember a few year back, i had an Athlon 2200+ and they never had IHS. I only ever seen one damaged CPU in all that time so yeah like you say they are quite durable but very brittle.

I wont take it off for a few months, or i will continue to RMA till i get a good one :P
 
Are you sure it's not block-ihs contact? How big is the blob of paste you apply as a large one might be hiding the bad contact on quick inspection. A wafer thin spread and a test mount could give an indication if that is the culprit.
 
Yeah pritty sure, 3 times with exactly the same results points me to believe its the CPU. I've done computers for years and never had trouble like I'm having with this.

When the new CPU arives today I guess it will tell the tale
 
Is it really running 75C at stock speed? that's definitely a problem.

Are the temperatures linear up to a certain clock point then jump? That's expected behaviour for these CPUs as they reach a point where more cooling doesn't really do anything and reach it sooner than Sandybridge.

4.6ghz is actually a pretty good clock for a 3570K but with good watercooling I'd expect 4.8 certainly. From the reports I've seen 5.0ghz requires a really good CPU sample.
 
well new CPU in with the Liquid Metal Ultra gives me a load temp of 55-60'c after 10 mins. the ambient temp shows no more tan 45...

this is a ridiculous drop in temperatures!

this is stock temps. give me an hour or so to play with overclocking and i will report them temps back
 
OK!

Previous over clock vs New

Ambient 73'C 65'C
Core 1 86'C 73'C
Core 2 90'C 74'C
Core 3 90'C 81'C
Core 4 86'C 82'C

Voltage 1.300V 1.320V

not bad considering the voltage is higher... ohh and the other thing, Coollaboratory Liquid Metal Ultra is awesome to apply!

Temps still seem a touch high for watercooling. My own 3570k @4.5ghz on 1.3200v maxes at 75c on the highest core under intel burn test, air cooled with liquid ultra paste.
 
yeah prolly just needs to reapply paste and check the block is clapmed down evenly, i got an odd core hotter than the others before and it was down to a little bit of dust that had got into the paste and stopped even contact.
 
Strangely, at idle my core 3 reads as low as 12c most of the time. The rest are in the mid 20's, it does however fall in line with the rest at load. Possibly a borked sensor, had the same on a q9550 a few years ago.
