So here is a theory; the advertised single core boost clock for this processor is 3.6GHz. could I set it to run at that speed by adjusting the clocks without touching anything else and have a stable system? It does it not work like that?

Thank you for the reply, I wouldn't have thought to look at that. All that being said, do you think it would be wise to give up on the idea of overclocking this thing? I went from a cinebench score of 460 at stock to around 570 at current clocks. The performance gain doesn't seem worth the risk of a blowout. Once again thank you, i have a background in computing but overclocking and voltage monitoring is new to me, I appreciate the insight.

Update: I dropped my voltages down a bit and dropped the clock to 3.7GHZ. I am idling at 35C with peak temps at 65C at 100% load. I used CPUZ and core temp and did not see any more crazy spikes or temps. Would it really be that much hotter going to 3.8GHz? Is voltage that big of a factor? I moved my voltages down by just a few notches as well.

I will try to tweak my settings and give you guys an update. I have never really overclocked my machine before so perhaps I made a mistake somewhere. I feel like my temps should be lower but I suppose this is a 95watt tdp processor. Does 55 degrees c under full load at stock-clock boosting to 3.2GHz sound normal? I am starting to see the issue with sticking too older hardware, not as many people use it anymore. Damn you budget!

Good Evening everyone, System specs: Case - NZXT Lexa s - Two intake fans 3 exhaust Motherboard - Gigabyte P55m-UD2 CPU - Intel Xeon x3470 - currently with 3.8GHz overclock Ram - 16GB Crucial Ballistix sport XT GPU - MSI R9 390x PSU - 700Watt Rosewill Green Series I just installed the Noctua NHD-15s in my LGA1156 system. I recently upgraded my CPU from an i5-750 to a Xeon X3470 (similar to an i7-870 from what I have been told.) I found that my Zalman CNPS9900a could not keep up with the stock cooling demands of the Xeon. I also recently installed the MSI R9 390x which has bumped my case temps up a bit. I overclocked it to 3.8GHz and am seeing idle temps of around 44 degrees with an ambient of around 25 degrees. The cooler is nearly touching the R9 390x which runs hot, hooray for backplates! I am currently running a 1-1 ratio fan curve on it. The GPU is idling around 47 degrees. When I first installed the cooler I was getting idle temps of around 37 degrees with the base clock. I noticed something strange when I loaded up Crysis 3 - Welcome to the jungle mission. My clocks started fluctuating, Core one spike at 9.2GHz and cores 2 and 3 spiked at 4.2 and 4.4 GHz respectively. To me this seems like it should be impossible. My temps under load are 73, 74, 71, and 77 (well over TJ Max). These seem unusually high. My video card topped out at 67 degrees C I am using a Gigabyte P55m-UD2 motherboard, I disable the turbo boost feature in bios. I used this setup as a basis for my overclock but took the voltages down a notch as well as the core clock. Is there something I am doing wrong? Should I re-mount the cooler? I have mounted several coolers in the past and never had a problem. Is the CPU cooler just that close to the GPU that it is absorbing heat? See attached for pictures of my system, my cable management is not the best, I did what I could given the non-modular power supply and the mid tower case. I appreciate any assistance or insight you guys/gals can provide. I will post my overclock settings when I can get to it.

Believe it or not I used canned air and it did not budge. The shape of the cooler didn't help.

I did do this when I swapped CPUs, I cleaned it with distilled water and a tooth brush.

Aside from the fact that the Hyper 212 evo performs the same/if not better than the H55. Is there any credence to the theory that the GPU could be causing the CPU to heat up and that having a cooling source/rad further away from the GPU might result in lower temps? Currently the case is setup for positive pressure. I wonder if seeing it up for negative pressure would make a difference. That might be a question for the air cooling forum.

I bought the CNPS 9900 because the reviews that I read were showing slightly better cooling. Maybe I should try re-applying the thermal paste. I used AS5 but have the Zalman thermal grease. I don't know that it would make a difference though. I remember watching the LTT video on thermal paste application so I don't know if it would make that much of a difference.

I believe that the GPU is causing the temps to be higher because with two HD 5770s (rear exhaust) was getting idles of 30-32C and 45-47C under load. This was with an i5 750 OCed to 3.7Ghz. I worry about the larger air coolers because, as is the case with this cooler, they get very close to the GPU. Unfortunately my case is a snug fit and my wife would kill me if I said I needed a new case after spending $330 on a GPU and $50 after a perfectly timed HDD failure.

Good afternoon everyone, I am having an issue with my recent MSI r9 390x purchase. The card is absolutely wonderful but this thing is HOT. It doesn't help that my case is more compact and my current Zalman CNPS 9900 (cooling a Xeon x3470) is within half a centimeter of the backplate for the GPU (see picture below, ignore the dust, it is no longer there.) I get idle temps of 43-45C with the fan being at 1400rpms and loans temps of 67-69C at 3.1ghz with the fan at 1700-1900rpms (loud, with a lovely buzz at the top end). I have a NZXT Lexa S case with three 120mm fans as intake (One side, one bottom front, one strapped into the top drive bays with zip ties). Two fans are exhausting one 120mm rear and one 140mm top. When I turn the fans up to 100% I can keep my CPU around 68-71C but it sounds like a jet is taxiing for takeoff on a runway. My GPU stays around 74-78C under load. My question for all of you is the following: Would adding a Corsair H55 help with temps and allow for mild overclocking? The X3470 advertises turbo boost clocks of 3.6Ghz but I cannot get anywhere near that number. My thinking is that top mounting the rad would give enough distance from the GPU to allow the CPU to cool effectively. I bought the H55 two years ago when my H50 block leaked, but replaced it with the Zalman due to fears about the new block leaking again. How worried should I be about future leaks/is there anyway to ghetto rig a catch system for leaks? I am super paranoid about damaging my new card. Thank you for you assistance/opinions

With those CPU temps do you think over clocking is out of the question? Would changing the cooler to the corsair H55 make any appreciable difference? I bought the H50 years ago and had it leak due to the stiff hoses. Fortunately the HD 5770 cooler was clogged with dust and was hitting 95C under load and instantly solidified the liquid it hit the card. I submitted a warranty claim and was sent the H55. I have been apprehensive about installing the cooler so it has been sitting in a box for the past two or three years.

Under load I am getting 76-79C on the GPU and 65-68C on the CPU. I created a custom fan curve, because I was getting 56-59C with 20% fan speed on the cooler. Now I'm getting 52C with 35% fan speed at idle. I was thinking the same thing about the GPU causing the CPU to have higher temps.

Good morning everyone, I posted this in air cooling originally but do not feel it was the correct forum. I am not sure if this is the right place for this, but here goes nothing. I have a NZXT Lexa S case with two exhaust (one rear and one top) and two intake fans (one front and one side) from a build I did in 2009/2010. I originally had two reference blower Sapphire HD 5770s in crossfire and an i5-750 at stock paired with the Zalman CNPS 9900 because reasons. I used to see idle temps of 45C for the GPUs and 33-32C for the CPU. I recently made some changes to my system in the form of a Xeon X3470 currently at stock and a MSI r9 390x. The 390x nearly reaches the max card length for my case. I am seeing GPU idle temps of 54-59C and CPU idle temps of around 37-39C, my ambient temp is around 25C. Am I being paranoid or are these numbers a smidge warmer than they should be? I realize since the GPU is now exhausting internally three case temps will be higher. Unfortunately buying a new case isn't an option because my wife has veto power and I just spent 330 on the GPU and had a hard drive failure two days after i installed it so there went another $50. Should I try getting some better case fans or am I okay with these temps? Attached is a picture of how tight it is inside the case. (disregard the dust buildup I just cleaned it and it is no longer there.)

Just to update you, I purchased and installed the X3470. It is wonderful, it performs much better than the i5-750. I am using a Zalman CNPS 9900 and at stock speeds I see temps at 36-41C does that sound normal?
