Scorching Temperatures on Custom-Loop 4770k...Something is Very Wrong.

post #1 of 6
Thread Starter 
Idle temps are around 28c-33c, but during stress tests, my max temps are pushing 87c-90c on all cores. I've exhausted almost every option, and I'm at a total loss. Quick rundown of specs:

4770k OC'd to 4.5 GHZ 1.24v (stable)
ASrock Z87 Extreme6 MOBO
2x EVGA Geforce 780 SC's SLI
1200w Corsair PSU
Crucial Ballistix Elite 16GB RAM
Corsair 800D Custom Case (Fill port mounted in top front connecting to EK Reservoir, 1 fan intake on back, 1 fan on HD bay, 1 fan pushing air up mounted under pump, 6 Gentle Typhoons mounted on 360 rad)

Mobo Settings: 4.5 GHZ Override, .005v offest. C1e Enabled, all other C-States on "Auto". TurboBoost, SpeedStep, and HyperThreading are all enabled. All fans and pumps are set to max when stress testing.

Cooling Components:

EK Supremacy Copper CPU Water block (Properly seated with IC Diamond)
PrimoFlex Advanced LRT 7/16" ID x 5/8" OD Tubing
Swiftech MCP 35x Pump w/ Heatsink
EK Bayspin Reservoir
XSPC 360 Radiator (custom mounted to the top with shroud, 3x Gentle Typhoon fans on the bottom of the rad, 3x Gentle Typhoons on the top pulling air from the case and pushing it out)

OCCT LinPack Test with AVX checked runs my cores up to around 87c-90c. Aida64 with FPU checked gets it up to 87c as well. BF3 and Metro Last Light have my temps at no more than 63c.

I have a proper flow configuration (Res>Pump>Radiator>CPU (inlet)>Res). I'm kicking myself for not having pics since I'm at work (will take some when I'm home), but there are NO pinches, harsh angles for my tubing. Radiator has been flushed using distilled water and a 2 hours pump/filter cycle to collect the debris.


After filling up my PC with distilled water, I did a leak test (passed) and bled the system (Rocking/flipping/tilting)....HOWEVER, I noticed that there was a gurgling/sloshing sound in my radiator that wouldn't go away, even after a week. It's now week two, and even after more drastic tipping/flipping, shaking of the case, while I can hear water flowing at a decent rate, uninterrupted, if I tilt the case in one direction or another (side to side, front to back), it sounds as if all the water is sloshing from one side all the way to the other...correct me if I'm wrong, but isn't that radiator supposed to be completely full, thus not allowing for ANY free movement of water?

I understand Haswell is a hot son of a gun, especially with the voltage I'm at, but what's concerning me is that I'm using some high end cooling components, yet there are guys on here running higher volts, higher overclocks using cheapo all in one water coolers and are at full load in the 50's-60s Celsius.

Sorry for the novel I just wrote, but I'm just trying to get some experienced feedback on why my temps are so damn high. I think de-lidding for me is pointless because even when I throw something like 1.3 volts (which I am NOT comfortable using) at a 4.6 - 4.7 overclock, it's BSOD city with only 20 seconds on the desktop! I'm fine with 4.5 GHZ (I've heard many aren't even that lucky), so I at least know I have a solid chip for the next few years and I don't need to worry about obtaining massive temperature drops to power high voltages.

Any help would be highly appreciated.

We have a similar set up.

At 1.24v, those temps are not abnormal, abet a little high, even for a custom loop. You can try reseating the waterblock and see if that helps. As you mentioned, a delid may be your best and only option if you want cooler temps. I am running 1.35v and my temps don't go past low 70s. My volts would not be possible without a delid.

While high, you will rarely see those temps in regular gaming / operations because stress tests are peak usage and normal use is almost never at that level. I personally wouldn't worry about those temps.

Appreciate the response.

I spoke to some of the guys over at frozencpu.com and from the sounds my radiator is making...they're betting almost 100% that I've got a giant air pocket that's causing the high temps. I'm about to take the radiator out and flip and shake the ever living piss out of it to try and get that thing completely quiet.

It makes sense...any sloshing/stream-like sounds in there means that the radiator isn't full, which is no bueno.

If it doesn't work, I'm going to take everything a part, and post up some pics of the setup.

Most rads have a top bleed port that you can unscrew to let out the air. Does you rad have that?

I'm fairly certain the ONLY rads that has that is the Alphacool UT series, but there may be a couple others. Anyways, I'm almost positive the XSPC radiators don't have them.

Back to the OP, even if you do fix your radiator you will most likely need to delid your CPU to get notably lower temps. The major issue with Intel CPUs seating isn't the use of poor quality TIM, which they do use, but it has more to do with the quality of their mounts, which very from chip to chip. Sometimes there is quite simply a large gap between the IHS and the CPU die causing poor heat transfer.
