Nrog091 Posted April 5, 2013 Share Posted April 5, 2013 Hey guys, just finishing my new build. I have an AsRock extreme4. The instructions say "attach the pump to any 3 or 4 pin header on the motherboard" I was just wondering, i have a pwr_fan header (3pin) and a cpu_fan1 (4pin). Which would you suggest to connect the h80i pump to? Thanks, Noah Link to comment Share on other sites More sharing options...
Speed Posted April 5, 2013 Share Posted April 5, 2013 CPU. Doesn't make a whole lot of difference because the connector only has one wire; the RPM reporting lead. The PWR connector is provided so that the system can monitor the PSU fan RPM if it has a dedicated reporting lead. Link to comment Share on other sites More sharing options...
Nrog091 Posted April 5, 2013 Author Share Posted April 5, 2013 Thanks for the info. I am oc'd to 4.00ghz and I am getting temps of 88C 5 mins into running Prime95. This seems high? edit: reseat pump/heatsink.. im 26, 34, 29, 16 @ 1.5% load. Does this sound okay ?? Link to comment Share on other sites More sharing options...
Speed Posted April 5, 2013 Share Posted April 5, 2013 88C is high, yes. Low to mid 70s should be your load maximum. The second set is more in line but core#1 (34) is a bit high compared to the others and core#3 is low. What do they go to under load? How did you apply the thermal compound? Seems that there may be a void in there, although it may even out after a couple of prime95 runs which would further spread the thermal compound into a more homogenous condition across the interface. Early temperatures can be off by a significant amount until burn-in has taken place. Link to comment Share on other sites More sharing options...
Nrog091 Posted April 5, 2013 Author Share Posted April 5, 2013 Thanks again for the reply. I went with the pre-applied thermal compound on the h80i heatsink. Should I order some different stuff and try that before I pack this thing up to return? :) Link to comment Share on other sites More sharing options...
Speed Posted April 6, 2013 Share Posted April 6, 2013 Reseating a heat sink without removing, thoroughly cleaning using an approved solvent and then applying fresh thermal compound using the stripe or rice method, depending upon your CPU, is not a good idea. Bubbles and voids will be trapped in the old compound, which is most likely the cause for that 34C core. Link to comment Share on other sites More sharing options...
Nrog091 Posted April 6, 2013 Author Share Posted April 6, 2013 Hey Speed. I cleaned CPU and the h80i heatsink with rubbing alcohol and qtips. Took a lot of time, making sure there was absolutely no left over residue. Went ahead and used some OCZ Freeze in a pea-sized shape int he middle of the CPU. Running prime and within 5 mins my package temp in HW Monitor is 79-87C @ 4.4ghz oc, 39C Idle edit: This is also with corsair fans on quiet setting.

Speed Posted April 6, 2013 Share Posted April 6, 2013 OK, good rubbing alcohol or regular old? There are two kinds. The one to use has less water content. You will not be able to see any residue. It will be in the microscopic cavities of the metal. This is why you cannot touch the surface. Fingerprints, and the oils that they leave, will fill the cavities and the conductivity will be hampered. A Q-tip is OK for a start but a coffee filter is best to do a final cleaning. Any small filaments form the Q-tip will diminish the contact patch. It is a painstaking and exacting process that should not be deviated from. Go here to get the best method for your particular CPU: http://www.arcticsilver.com/instructions.htm If, after that, the temperature is still in the 80s something needs to be done because that is too high.

Nrog091 Posted April 6, 2013 Author Share Posted April 6, 2013 Yeah... not sure. Took your advice and right after I read your post I went back to playing with the cooler. I took a lot of time yet again cleaning all the paste, using rubbing alcohol, qtips and then coffee filters. Read the technique in your link and went with the straight line method. Prime 95 under load was still 80-89C under load, 32-39C idle @ 4.4. I turned down the OC back to stock and honestly temps were only a few degrees cooler. Starting to look at the CM Evo if I want to save some money... or maybe the Noctua DH-14 if I want to spend a little more :) Link to comment Share on other sites More sharing options...
Speed Posted April 6, 2013 Share Posted April 6, 2013 89C? After going through all of that, if it were going to get better, it would have. I'm unfamiliar with AsRock boards. What CPU are you running and what are the voltages? Could be that the voltage is unnecessarily high, which would create higher temps. Bear in mind that temps will generally be a tad higher until the thermal compound has a chance to thoroughly unify itself with the metal. Sometimes takes quite a while. I think the doc that I pointed you to has times listed for the various compounds. Link to comment Share on other sites More sharing options...
Nrog091 Posted April 6, 2013 Author Share Posted April 6, 2013 asrock extreme 4 w/ a 3770k. I am using a pre-configured OC setting through my mb bios to 4.4ghz. cpu vcore voltage in hw monitor is between 1.128 and 1.2. Link to comment Share on other sites More sharing options...
Bryman Posted April 6, 2013 Share Posted April 6, 2013 ok voltage seems normal...but i can tell you i run 4.5ghz 1.3 volts and at 100% load small fft it hits 100-105C easily...and i have the H80i with the pre applied thermal paste it came with...with 4.4ghz 1.25 volts its only about 5C cooler...im sure 4.2ghz 1.2 volts would be another 5C cooler but anyway point is...yours is about the same as my temp so i wouldnt worry too much is a 'little' high though Link to comment Share on other sites More sharing options...
peanutz94 Posted April 6, 2013 Share Posted April 6, 2013 srock extreme 4 w/ a 3770k. I am using a pre-configured OC setting through my mb bios to 4.4ghz. cpu vcore voltage in hw monitor is between 1.128 and 1.2. This is often the case with pre-configured OC's. They often add more voltage to components than what is really necessary to maintain the overclock leading to higher temps. I really would suggest looking for overclocking guides for your MB or CPU to learn how to do it manually. More often than not it will lead to higher overclocks at less voltage and lower temps.

Bryman Posted April 6, 2013 Share Posted April 6, 2013 that voltage isnt high...it took almost 1.2 volts just to make it stable at 4.2ghz...so i would say for a 4.4ghz overclock that 1.2 volts is NOT too much...as long as its below around 1.25-1.3 he should be fine...in fact the stock voltage is 1.2 so 1.2 isnt high at all Link to comment Share on other sites More sharing options...
