Recently RMA'd (new) i7-3820
New Asus Rampage IV Formula
Asus Radeon HD7850
Corsair Vengeance (4x4gb) @ 1600mhz
Corsair HX1050, Bottom mount, Fan Down (intake)
- this doesnt really matter as the HX1050 Gold doesn't spin until hot and then its an exhaust anyway, I have spot on the bottom of the case that intakes cool air right where it sits.
Corsair H80 w/ stock fans set to high.
-tried mounting with rad hoses on top, bottom, intake and exhaust, currently running it outside the case for testing.
Intel 330 Series 180gb SSD (boot)
OCZ Agility 3 240GB (data)
WD 2TB Black (data)
Coolermaster Stacker STC-T01-UW w/ 3 - 4x3 modules (each has 120mm fan intake in front)
Nortua NT-H1 Thermal Paste
No cables in the way.
Currently testing 4.3ghz Stable at 43x100 with ddr at 1600mhz, Auto voltage (1.38v loaded priming)
My ideal speed is 4.625 based on my benchmarking each speed from stock to 4.875ghz. This gives a balance of vcore/temps and a reasonable boost in speed.
Best Idle temp at this speed is Avg 40c (across all 4 cores)
Best Max temp at this speed during prime + furmark is Avg ~73c (~78-80c max core)
Im nowhere near what people are getting at these ambient temps. This is even with the rad and fans outside the case.
The H80 just cant carry the head away from the cpu any better than 40c idle, Avg 73c max. My highest core gets to ~78-80c.
Stock i7-3820 not overclocked I get about 32c idle, 68c max
Any Ideas? Even ~5-10c better max temp would be nice.
Ive reseated the block 4 times, with all similar temps. I wonder if its just not seating right or is my pump on the way out?
I *MAY* have applied too much thermal paste.... could that skew my temps 10-15 degrees ?
Nicely presented (complete) info! While your temps are reasonable, I agree they certainly don't match up performance wise w/other H80 users even considerering the hotter running X79 platform.
My 1st thought was mounting, but it seems you addressed this with several remounts ... but many have had signifigant improvement with an extra crank of the mounting screws, it may seem like your overtightening , but try an added 1/4 turn beyond what feels normal/secure ... but be careful use good judgement. Also on the next mount check the H80 block and CPU for excessive concave/convex deformities with a straightedge ... you may be a candidate for "Lapping" your block and/or CPU-HS .... I noticed you RMA'd your 3820 once already? Maybe there is a hard to detect excessive heat problem with your mobo?, your temp drops at idle showed typical improvement when you re-enabled "speed step" I'd leave it enabled for 24/7 OC. Check your load temps again with just P95, without Furmark also running as that really stresses the mobo/etc in addition to the cpu and is generating NoN real-world heat and stress on the whole system ... Next is your case, even being an oldie but goody and you've adressed cables (nice job) and added aux fans, try the whole process with your side cover removed and a box fan blowing inside and see if there isn't 4-5c improvement just there alone?
Your temps do seem High and while I'm on Z68 and have an H100 I pulled these old stats from my initial shakedown/OC session trying to match your situation with ambients/ cpu volts and putting the H100 on "Low" setting which pretty much equals an H80 on "High" ... and Last but not least what monitoring programs are you using?
I like Real Temp [HERE]
and HDMonitor [HERE]
2500K@4.6 - CPU-Z (volts) i1.032v / L1.384v / Real Temp (watts) 78w
Hyper PI 0.99b - 32M - 8m 19.231s A70F/21c / i31-26-28-29c / L57-58-56-56c
and here's a P95 run at 4.2GHz but 80F/26.5c ambient
Prime 95 (Blend) - 20min A80F / i34-31-30-31c / L53-56-55-54c
Hope some of that helps

Purchased a h50 and Antec 902 case 3 years ago, then put off the build because of reported heat issues on core i-7 and gtx 400-500 series cards.
I have continued to limp alng with a used c2d e6600 on an intel mobo in a generic box, that I got from CompUSA's training room, when they went under (2007?). I download usenet vids and game (steam) on it. (+GTX 260 SP 216)
Core i-5 3570K CPU
Intel Z77GA-70K Extreme mobo
Corsair VengenceLP DDR3 1600 16GB kit (4x4GB) (CML16GX3M4A1600C9b) *certified w/mobo
H50 Cooler w/ x2 Couger Vortex HDB Fans (1200RPM , 60cfm, 1.73mmH2O, 17.7db)
EVGA FTW GTX 660 ti Superclock 3GB w/ Backplate
Seagate 1TB sata II + Intel 520 120GB (RST & READYBOOST Partitions)
Corsair TX850 PSU
Antec 902 Case
H50 is mounted push/pull intake from the rear fan mount. Rad is oriented tubes down (I'm a hydraulics specialist in the real world).
Room is 23c ambient. TIM is stock. It runs cold. I have an infrared thermometer to verify reported temps.
Prime95 CPU temp (multiple tests 10min -3 hrs)
idletemp: 22c +/-
torture @ stock 3.4ghz: 52c +/- (stable -no fail)
torture @ oc 4.5ghz: 62c +/- (stable -no fail)
The air exhausting from the H50 radiator is 3 degrees celcius warmer than intake air. The rad itself does not get hotter than ambient. The case is not warmed by the exhaust, in fact with the side door off, the fans blow cold air directly onto my face, it cools the mainboard components aswell. The Couger fans are silent, when i put my head into the case i can only hear the antec branded 120mm front fans and the BigBoy 200mm above. My GTX 660 ti, at idle runs +10 degrees above ambient, much cooler than my GTX 260. The TX 850 PSU is amazing compared to the TX 750's I have. Under full Prime95, the fan doesn't even spin up (85 F-101 F). The hottest spots on the mobo are the bridgechip, RAm and capacitors (30-35c)
I'm a noob at this oc'ing and tuning. Intel visual bios was simple but i read, underwhelming and conservative in oc'ing compared to other mobo's. As a noob, I'm ok with that. I was very impressed with the quality of my old DQ965GF board. It's been running 24/7/365 and constantly downloading/gaming/surfing/dataserving for 5 years with only a few reboots/year. I'm passing the old rig onto my daughter, who's six and gaming on my wifes casual steam games already.
_________ One Question ?___________
The ram is reporting as 0.74-0.75 volts in Intel Desktop Utilities. Bios specs are asking for 1.5v. I troubleshot the RAM in pairs both syncronous and asyncronous modes and swapped , looking for a bad one. I changed oc speed from 1333 to 1600 and back again, used automatic and XMP profiles... no change in voltage. I did update the bios when i installed the OS, which required a CMOS purge by removing the battery to get it to reboot after the bios update. Can anyone give me more insight into this ram voltage issue. Google is of no help, searching for undervoltage and underclocking only gives advice on intentional downclocking... not unintentional. Searching for an arbitrary voltage like 0.75v doenst find searchstrings for alternate undervoltages like 0.76v. I have a support ticket in with Corsair RAMguy. Maybe you guys can save me days on the phone talking to intel. Has passed Memtest86 v4.2 . [ Doing more research I realised the "LP" designator on the RAM is "low power".. but it should be 1.35v ... or is 0.75 v normal? Is the intel software giving me a bad reading? ... why does the bios report 1.5v instead of 1.35v LP?]
Welcome - Nice build and another well presented question
Not being to familiar with Intel boards/bios' ... but I can safely say your ram would not even boot @0.76v so that is either a software reading glitch or it's a confusing/mis-labled sensor ... I'd only trust your in bios voltage readings for ram ... AND to take advantage of the extra low voltage ram modules you will have to "manually" set 1.35v in the bios as even with a bios update even Asus/ASRock/Gigabyte (what I use) don't always get the XMP settings right with every manufacturers IC's ... in reality I'd leave the modules @ 1.5v especially for overclocking stability!
EDIT: I missed your "Last thoughts" the 1st go around
... Well said! and I agree with most of your observations ... your quite an opinionated guy, We like that, you'll fit in "Nicely" around here if you choose to do so ...
Sorry if I offeneded you with the straightedge/lapping comment but it works quite well for those that pursue that avenue because they don't want to hassle an RMA process or just want that "mirrored finish", and most I know don't use regular sandpaper/ what gave you that idea? Additionally most aren't as technically skilled and equiped as you [You have ABLAP diamond lapps (1 lightband flatness), monochromatic light sources and optical flats for checking flatness.] Nice! ... But I'm sure your well aware not all components are released to market with original specs, too many get by QA these days, and yes some are so bad that they will show up with a simple inexpensive machinists/jewelers straightedge

I cant push pull with a h100.
Definately the H100 ... it will slightly outperform an H80 even without a Push/Pull setup and depending on your OC and tolerable temps will run Quieter! ...

my temps never peaked 45c with push pull. I had swapped out the h60 for the NZXT Kraken X60 which is a 280mm all in one cooler. i wont have that till wednesday but going to run some test on it. The h60 h80 and h100 honestly have a hard time cooling the new intel cpu. i have the 3770k oc to 4.6 at 1.25vcore and my room temp is probably 15c (from Minnesota and its freezing here) and mine temps out at 68c to 80c. currently at 38 to 40 on all cores.
Not a fan of corsair Coolers after this last one

I'll agree your temps seem high even if you have one of the "Hotter" running 3770's [@4.6 at 1.25vcore] especially with pretty ideal ambients of 15c. For many it depends if they got a 3770 with a good mounted IHS or a sloppy one? When OC'ing Ivy Bridge I see temps/volts all over the place ...
BUT if you don't mind doing a semi-modded mount of the Kraken X60 (280mm rad) then this may be just what the doctor ordered for you, especially if you don't want to give in to a full "Custom-Loop" because the X60 will cost almost as much! It's hard to find any reliable head to head comparisons of the Krakens but this looked promising [HERE]
... looks like 1c-6c improvement (depending on setup?) over the H100 on "High" with a 3570K 4.6GHz @ full load and the Kraken probably will run quieter
with the naturally engineered quieter 140mm fans
... but again, may depend on the setup and type of fans?
It would be very interesting to see your H100 vs Kraken X60 head-to-head results with all the details if possible!

Anyone who has been in this thread helping will be put on the draw list. Once I get my WC setup of course. Couple weeks xD
Wow ... that is very generous of you
This thread has been a lot of fun! ... I hope it goes to someone that will use it on their GPU ... my 10 cents Edited by TomcatV - 1/7/13 at 2:49pm
