Hi, i just bought an i7 2600k from a close friend and i my temps reach almost 80-81c on the 2nd and 3rd core, while the 1st and 4th reach almost 65-69c.

It seems that my custom loop does not work well, the waterblock has some scratches and im thinking thats the main problem. What do you guys think?

This is my custom loop, do you guys see something bad? :S

Sorry for my english.
 
remount the waterblock its probably bad mounted and not making good contact.. be sure to mount in a cross pattern so you can be sure it was correctly seated and also be sure to apply the same pressure across the block... what pump are you using and at what speed its working?.

Hi, Araxie. We already mounted quite a few times... like 5 times whit the 2600k and another 5 times whit the 2600 non-k, almost the same temps.

It is the XSPC Raystorm 750 EX240 kit... i think the pump is 750 lph no speed controller so it must run at full speed. http:///6BVZMu

Also, i use AS5 as thermal paste.
 
10c difference in temps in between cores isn't uncommon.

Although, if those are your temps at stock speeds, then something is wrong with your mount.

Another possibility is flow problems (cpu block might be gunked up if its a used block or radiator might be full of air still).

Light scratches on block aren't a big deal, only big scratches that you can feel with your finger/nails would be an issue.

4.6GHz isnt stock speed... and the kit is brand new.
 
The mount is more than likely the problem....scratches on the copper would not make that big of a difference (Really will make not even a degree more than likely) in your performance. Make sure its on there tight (To the point you think the board is bending)
 
Remount the CPU block. I had something similar happen to me on my GPU block. Once I remounted it, it went from 80+ Celsius to 40-45 Celsius on my custom loop.

Basically I have that same processor so you should be getting around 40s or so.
 
guys... air in loop hurting flow, so easy to do with top mount radiator.

I need to know about your pump and reservoir setup?
how many fans on that radiator?

I already mounted like 4 times and im sure that i mounted well same temps whit the last 10 mounts. 2 fans as exhaust in the rad... and i clean the block and the cpu whit alcohol so theres nothing that can make the thermal compound work badly.

It is a combined pump/reservoir wich goes to the rad and from the rad to the waterblock and from the waterblock to the pump/reservoir. I feel how the waterblocks gets cool when the pump is on and how its warm when is off, so im getting good water flow.

Its only cost me $149 dlls + plus tax, is not a expensive custom loop maybe thats the reason for my bad temps.. but a friend whit the same, i mean my 2600k gets the same temps at 4.6GHz whit a noctua nh-d14
 
Try using a good air HSF (at stock speeds) and see if your issue continues. If mounting is ruled out as a possible cause, it's possible your water block may be partially fouled.
 
Yes, the mounting is ruled out. I can try to open the block and see if theres any wrong but i think i prefer to buy a new one... it can be alot of things, waterblock, reservoir/pump or rad :(

It's possible the problem is elsewhere (other than the block), but I suspect the block just due to the massive temperature distribution problem between the cores (which is why I suggested an air HSF to rule out possible poor die to IHS contact). It could also be due to really low flow in the circuit (due to a cause other than the block) but I'd think in that case that the difference between the cores wouldn't be so pronounced.

My $0.02...;)
 
Can't believe nobody pointed out the obvious...get some NPSH on that pump. Mount the pump completely under the return line from the radiator to the suction side of the pump and see if that helps. But for the love of god move it out of the top 5.25" bays and set it on the HDD cage or on the bottom of the case and see if that does anything. If it doesn't then you're best off taking apart the loop and giving it a good cleaning or buying a new block.
 
Im going with either bad mounting, or uneven thermal paste. Doesn't matter if you mount the block 100 times, if you mount it wrong every time. :)

Net Positive Suction Head is the obvious answer here? I had to look that up. It's a pressure measurement. Researching this term quickly moves you to firehose couplings. The OP is using a bay res with a pump on it... He can't move it for the love of God.

But yeah sounds like bad CPU block. No idea how common that is but I have several defective parts from my recent build. Interestingly the are all from Aquacomputer.
 
For the love of all that is holy look at the parts.....He has a bay res pump combo with the 750 pump from XSPC .... It doesnt matter as the pump is submersed IN the water so it has the pressure there. If the issue is along those lines the rad needs to be moved down, but again it should not be an issue there could be air in the lines as mentioned, however that would not cause the difference in temps between cores. That is why all of us have been saying its with the block, and for this issue pretty much the only reason for it to happen is because of a bad mount. As the OP stated its a new block, there shouldnt be gunk / plasticizer in the block to restrict flow The flow wont be an issue as its the only thing (With the exception of the radiator) that is in the loop.

Thanks everyone :) Well... those are my temps now at 27 ambient.

The friend who sell me the 2600k was having the same difference between cores but he still was getting the same temp as me.

well there are so much un-calibrated sensors in the chips.. which will report very inaccurate the temperature readings.. as a personal case, my 3770k its very uncalibrated at idle and you can see some serious drop of temperature even at lower than ambient temperature its more or less 4 or 5C uncalibrated under deep idle lower spikes.. so it may say its at 23C when its in fact at 28C.. that things happens, which its really important its they are accurate at the trigger throttle point which its 98C in your chip..

So i have nothing to worry about? I dont do much OC but sometimes will be great when im rendering or doing something and i need the extra poweeeer... also i disconnect the rad fans and the water and the hoses start warming up not instantly but 5-10 mins after. This fans are the stock ones that comes whit the wc kit, i think i need

I dont feel that much aire pass through to the rad... so i maybe need to change the fans. Im thinking on the Corsair SP 120mm, any recommendations?
 
if you want to go with Corsair SP120 go with Performance they are cheap fans... if you want to spend and if you can find search for Gentle Typhoon AP15(IMHO the best radiator fans ever made).. you can also check for Noctua NF-F12 (my second choice of fans after Gentle Typhoon AP15) or noiseblocker B12-3..
 
Ouch, just noticed 27C ambient. What is the rear fan doing, exhaust or intake? I think your ambient temps are running you up more than anything.

Yes Kwisatz and even in cold days my room is pretty warm (i love it) but i dont like the temps at 4.6 even when i know my friend has air flow in his room he is getting better temps whit an air cooled cpu fan, hahaha.
