Hey guys,

So basically I have an issue with heat being removed too slow.

I am running a De-Lidded CPU, direct to EK supremacy with naked Ivy mounts.

I am running the CPU at 1.3v with a 4.6Ghz OC.

Now gaming or doing anything normal even Cinebench R15 max temps are around 72c.

But as soon as I run Prime95 (max heat setting) or IBT my CPU hits 100c in a matter of seconds.

My loop consists of:
CPU Block: EK-Supremacy Clean CSQ
Reservoir: 2x EK-RES X3 250 Reservoir
GPU WB: 2x EK-FC Titan - Acetal+Nickel
Mobo WB: EK-FB KIT ASUS M6F
Pumps: XSPC D5 Vario Pump x2 with EK-D5 Dual TOP G1/4 CSQ - Acetal
Radiators 360: XSPC AX360 Triple Radiator
Radiators 480: XSPC AX480 Quad Radiator
Tubes: Acrylic Tubing
Fittings: Bitspower Deluxe White fittings

Pumps are on max speed and seem to be pumping pretty quickly.

Does anyone have any ideas?
 
You appear to be describing insufficient flow rate, But I wouldn't have thought it would be an issue with that setup, especially with the pumps set to 5 as that's 1200 litre per hour.

5 blocks and 2 rads is by no means a basic loop, but I am running 4 blocks 2 rads (Only one GPU) + dual D5's with EK top and I was able to get 4.5GHz out of a i7 3820 with the pumps on setting 2...

*EDIT*

Looking at your build your only have one motherboard block, so its 4 blocks 2 rads...

If it isn't an issue with the coolant being unable to get the heat away from the chip fast enough it may simply be a case of silicon lottery and the chip being at it's limit :(

Is this the project Ethos and Cube rig?

If so, What is the temperature inside that desk? Pipe runs and bends will also cause head loss in the system. Although I would have thought 2x D5 suitable. Possibly insufficient exhaust although I have not read the full thread.
 
Ye its for my desk build.

Not sure of the temp from inside the desk itself but its not hot or anything.
Maybe about 3/4c warmer.

But agreed it may be silicon lottery.

But it just feels like I cannot get the heat away quick enough.
The liquid itself never gets over 35c.
 
Prime 95, like Linx and several other stress testing programs use AVX coding which hammers Haswell and makes it draw a extra 0.1v vcore. That would account for some of the extra heat. Try IBT which doesn't use AVX and see what your temps reach on that. As you are also running a naked cpu the heat is being removed from a smaller area which could also account for the extra heat.

How's that?Smaller area?He has put water block directly on DIE( only one Thermal Paste).Heat is transfer from DIE to IHS (Thermal Paste,****** intel one) then to(Thermal Paste) water block.
No one asked what Thermal Paste did you use?
I've seen drop in temps on my hd 7970 (koolance waterblock,Artic Silver 5) from say 60-65 (not sure now) to 54 when I used Coollaboratory Liquid Ultra.
Gelid Extreme should be good to,some test claims it is few degrees better than CLU.
Change Thermal Paste(clu or ge),then you'll also find out how well block seated on die,cos that might cause problem as well.

I would agree that running bare CPU to block with one layer of paste is better than CPU>intel paste>IHS>paste>block.

The fact you have a local ambient of +3 to 4C in an desk size enclosure as a heat dissipator compared with a room size enclosure at ambient is more likely to cause overheating.

Cases should ideally have enough airflow to reduce the internal temps to near enough local ambient room temps. maybe you need a summer glass top with cut outs to allow warmed air to escape.
 
hmmmm im using Cool Labs Liquid Pro on the Die of my delided 4790k and then ic diamond on the ihs of the heatspreader :D

20+ load temp decrease, it does work :) i would not advise doing it on a GPU die though as they usually have far more vrm/ic`s on the outer part of the surrounding die.

It wouldn't have been the thermal paste that dropped your temps so much, it'll have been the reseat process.
 
As I wrote,I'm not sure if before temps were 60-65 range(more like 62) and definitely it was down to thermal paste,mate.My friend had the same result and he recommended me CLU.Maybe we both wrongly seated our blocks,you'll say?
Look on this graph:

So moral of the story is that changing IC Diamond to Gelid GC-Extreme would be a better option?

Also is it non-conductive and doesnt have any parts to scratch the die?

Game mostly.

Its just I cleaned out my loop and redid everything.
Took apart my CPU block to clean it out and now its not playing nicely.

Where before even on Prime or IBT it seemed much cooler, and wouldnt hit 100c at all.
(problem is I cannot for the life of me remember what it was).

Also I re-did my Overclock as I updated my mobo bios.

So it could be that the Mobo is just upping the voltage or just generally running hot.

But like I say gaming its not bad.
About 65c/70c across all cores.
4.6Ghz @ 1.3v
